    Cool Acronym madness: ITG CAI ON S3 8P

    A review of ITG's prototype CAI on the S3 8P.

    You have a Carbonia, why change for an ITG?
    So before I begin let me fill you in as to my choice. I'd been needing a kit for a while, and had been awaiting the Twintake from Forge for some time. My lease on the S3 is running out fast, therefore time is of the essence. Yes, I ran a Carbonia intake / filter which whilst at stage 1 was perfectly satisfactory, however since fitting the HPFP & Revo Stg2+ map there was a slightly flat sensation when accelerating from mid speeds. There were 3 likely candidates: Intake / DP / Cats. From a considered review of previous experience mixed with the opinions of people I respect, I decided to sort the filter first as logs had shown I was lacking air at the MAF, and to be honest exhausts are just overrated and horribly expensive.


    So who are ITG?
    I was introduced to Andy Jackson at ITG by RevoCarl, and got chatting as to the merits of their CAI system. I had always believed ITG to be a company that made filters for race vehicles rather than road cars, and it turns out ITG's client base is actually extensive on and off the track (Vauxhall VXR BTCC / Renault F1 / Red Bull Racing to name a few of the ones you'd instantly recognise).

    So what is there solution?

    This is the end product. See the girth on those pipes?! See the quality of the finish? See how tight the filter fits in the enclosure?! (Don't worry, this is an S3 affliction, and the Leon has far more space for the filter!). There will be some of you scratching your head now, wondering why this kit doesn't look like an Evoms, Forge or a Dbilas, with fancy logo'd enclosures. I will address these questions later, so stay with me for the 'science part' later on. I will be the first to admit, if bling is your primary concern you will find this system slightly 'functional' and lacking in glam. However, look closely and there is some VERY industrial and clever engineering, and as you will see in later photos an incredible level of attention to detail.

    So what does it offer over and above OEM?

    See the plastic pipe above. That is the pipe that disappears down the back offside of the engine from the MAF. Getting the spring clip of this baby requires some patience and a rather funky tool, but as you can see it is not the most efficient pipe on earth.

    Above is the ITG replacement. It is less restrictive than the OEM unit without the concertina effect, and is made out of robust silicone hosing. The piping diameter up past the MAF has to be consistent with OEM equipment (67mm I seem to remember) to ensure the MAF reads as it would in the OEM pipework (to keep the ECU reading accurately). The MAF connector pipe connects to this pipe (the alloy section to the left), and there is a beautifully crafted cut out which seats the MAF precisely. Another piece of silicone hose connects to this (furthest left), at which point the pipework expands out (can't remember if this is 89mm).

    If you look inside the down pipe (goes down the back of the engine), you can see they have even bothered to chamfer the hose just like the original to ensure the air flow isn't constantly disrupted by steps inside the flow path.

    The pipework has been maximised in diameter for good reason. This intake has quite a long flow path from the filter through to the business end, and with 3 right angles also in the flow path it actually benefits airflow through the bends to increase the diameter of the pipework a little (or so I am told). I don't understand the dynamics of airflow so I won't embarrass myself, but Andy has years of experience and the results speak for themselves so I will leave that point there. A result of using enlarged diameter pipework (in conjunction with a large filter surface area and type of material used), the turbo spools up so (and when I say so I actually mean SO) much faster. I'll be honest, I wasn't expecting that much from a CAI, however I had underestimated the restrictive nature of the OEM box I've been using. Whilst it served a purpose to keep the Audi service techs heart rates in the normal range, it was nothing but a blocker in stage 2 trim.

    The compromise
    In a perfect world, as Andy is passionate about quality, he would have loved me to have either relocated the battery, or replaced it with a slim line one (Audi TT's have this privilege bestowed upon them from factory. If so we could have fitted one of these babies:

    However, this is a compromise from a cost and convenience perspective I could not commit to. Big turbo cars would benefit from considering this as the filter would be able to flow well in excess of 400bhp due to its increased size. The one in the pictures is good for over 360bhp which mirrors closely with Revo's stage 2+ pack.
    This was not to be, so a conventional barrel filter was fitted with a surface area which closely mirrors that of an OEM paper filter. Due to the maths, the surface area of the filter can significantly increase/decrease the capacity to produce BHP in turbocharged cars, and although Andy did furnish me with the equation for this for the ITG foam and how it's BHP capabilities per cm2 area change I have to profess I have forgotten them :doh:
    It's quite a tight fit in the S3 as the adaptive bi-xenons are incredibly deep, and the rounded edge nature of the car further removes space. The Leon has the best space, followed by the Golf, Octavia and then S3

    Althoug this kit is currently in prototype form, it has advanced significantly from the previous 2 iterations, and now includes very solid mounting points, a decent rear heat shield to deflect heat from the exhaust, and enough give in the silicone hoses to ensure the MAF is protected from any significant vibration.

    The filter enclosure
    ITG have researched this parameter of the CAI in some detail, and have looked at various materials to take charge of creating a defined enclosure for this open filter. After much trial and error they have used a foam baffle, and this makes sense for many reasons. Firstly ITG foam is fireproof, so can deal with a great deal of heat. Secondly foam expands into almost any gaps, and by using light to test for breaches round the foam wall they have been able to produce an enclosure which only suffers a few degrees increase from ambient (this has been tested). So now your thinking, foam lets air through, so that means engine air can get into the enclosure. Yes it can, but due to the pressure of air coming in around the headlight and inner wing there is equalisation which holds this air back. Whilst we're on the subject of heat, being the honest and open minded reviewer I try to be, the alloy pipework in the main bay can get very hot. To reduce the price of the kit to a decent RRP (due very soon), they have elected not to include elaborate heat insulation jackets/tape for the pipework. You can get this from Agriemach or other motorsport suppliers if you find you want it (circa 60).

    So the foam goes in and the kit is finished. Not a supermodel in the world of CAI's but certainly a titan of excess engineering.

    On the road
    Once all the bolts were done up, the MAF transferred in, and the foam adjusted to hug the bonnet lid we were ready to roll.
    What I found initially impressive is that I was wondering whether this excess would lead to any odd side effects. I'm pleased to announce all was as should be, and other than a bit of gentle metallic rasp it was as OEM as you could wish it to sound pootling around town.
    Out of town matters took a turn, and this intake rasps....loud. Between gear changes you get a chatter from the DV as the pressures equalize out, and the surge of acceleration is; well relentless. Gone (completely) was the flat spot at 4k, and the car surged hard to 7200rpm, gear after gear. Quite literally a transformation, and one that forced me to apologise to Andy as I'd doubted that his efforts would have transformed the car quite so much. Remember here I am comparing to the OEM engine cover unit, NOT another CAI, but I would reckon that whilst there is way in excess of 10bhp improvement, its actually the torques that have benefitted the most.

    I'm confused - this is not a placebo effect. How does it work?
    My old intake connected to the slam panel to take air in. A very noble cause, and it makes common sense. However the size of the inlet aperture is quite small and restrictive. We tapped a large opening from behind the nearside fog light, and another point behind the nearside headlight to get airflow feeding the foam baffled enclosure and it provided a far more plentiful supply of air than was getting past the mouth of the Carbonio. This in tandem with the large diameter pipework and large filter increase the spooling capacity of the turbo therefore delivering multiple benefits.

    Should I buy one?
    It's the common practice of anyone who buys anything to tell everyone they should sell a vital organ to get one. I guess my summation is this. If you value performance above aesthetics this is a great solution. I actually warmed to the look of this once I'd had the chance to acquaint myself with the attention to detail, but even it's maker admits its not beautiful. Purposeful, yes. I think Andy appreciated my open minded perspective on this attribute, as it would be easy for an Audiman to value looks over performance. Pricewise it is going to sit right in the main ground at circa 300 (subject to kit finalisation). This is an incredibly fair price for the benefits. If you ever have plans to go BT, this kit offers a stage 2 perspective by moving/changing the battery and go way beyond 400bhp capability so has similar flexibility to the Revo staged kit. It's no surprise that as Revo use it, it has been extensively tested with this unit, so works an absolute treat together.

    When is it out
    About a month for finalised production versions. To register interest please contact Andy Jackson at ITG, or for more detail on ITG products visit the ITG website here.

    Any questions? Fire away.

    Top post, as ever. Glad to see you got it sorted and will be interesting to follow its progress, especially the foam used to seal.

    Another option is always welcome.

    Yes, but as every model seems to have a different space under the bonnet your solution will look quite different.

    Is your battery in the boot?

    To be honest I think it looks great! When it comes to performance I think looks are subjective. For example a Bugatti Veyron looks a lot sexier than it should do because you know what it's capable of.

    Well it has that effect on me anyway.

    I don't know a lot about the max tuned S3s out there but what CAIs are they using and for what sort of power?

    Are you planning to go BT?

    No, other than a decat I won't be doing anything else to S3. It's at a safe limit, and ideally I want a proper sports car next time. Feels at a decent limit, and I was just surprised as to how much this filter added to the overall effect as it's not a mod I associate with significant gains.

    I looked into the other offerings and whilst good they had MAF compromises or appeared to lack the outright surface area to supply the flow of air for 350bhp.

    THe guy who designs the kit was a jedi master of information on air intakes and even aero effects. It was very interesting to get some industry truths rather than urban myths about filters.

    Maybe the thread title isn't grabbing people!

    Yeah my battery is in the boot and my intake is seperate to the engine cover so I'm thinking I might be able to retain the cover with the ITG, plus I'll have quite a large area for the filter Thanks for the review and the info on this!

    Warren,you should of said you were at the factory I could of showed you some of the country lanes around Warwickshire to have a blast around,the ITG guys fitted a carbon fibre prototype to my S3 2 years ago which was nice (I think they thought it was the new one)

    Would be interesting to log some data before and after fitment

    It's exactly what I was looking for!!!

    As I didn't find it, I searched among all the CAI suppliers what I could find to build it myself.

    But finally Itg did it.

    I think, to make it perfect, Itg should design a custom Air box which fit the S3/A3 8P.

    Good review warrencox

    Good review warrencox
    They have a stunning carbon one, but you have to move the battery



    They do a hell of a range of bespoke kits:



    You should see the new RS6 filter housing. It sits over the engine in a carbon enclosure like a huge dome. It's astonishing (and likely to be over a grand!!! - but then if you can afford a new RS6 ).

    ITG tend to take on far more bespoke build filters than most manufacturers. Andy said very often they will try and take on jobs other manufacturers don't want to touch.

    And they're BRITISH. Another great reason to invest in our own economy, and help UK jobs. They said they have never been busier (which is good), but a lot of that is high end motorsport.

    THanks for all the kind comments above. I will try and record something as you have to hear this to believe it. It sounds amazing, and will shortly be sucking small animals out of hedgerows somewhere in the South East!

    It was a flying visit mate, and very last minute as my car felt sick - turns out it wasn't sick at all, just air starved. If I am up your way again I'll give you a shout.

    I'm off on 2 weeks holiday next week, but will get some logging done when I get back.

    Quote from Revo Kev on performance tests (Stolen from another forum):

    The guys over at ITG know what they're doing, and they're also willing to work with people to make sure they are 100% right... being that they're not a million miles from us we've seen a fair amount of Andy and the guys! No suprise that our cars all have ITG intakes on. Being in the lowly 1.8tsi A3 does have it's benefits as I've one of the lovely carbon boxes in my engine bay On that the ITG made an honest 13bhp from the 220odd it was seeing.

    There's an easy 10bhp from a decent intake on the 2.0ltfsi be it the K03 or K04... I honestly think there's pushing on for 15-20bhp on a stage2+ car. Our Cupra has a very similar setup to this and our TT has a very large aluminium airbox, both are very, very good!

    Z (aka pimp daddy!) - with the stock airbox you'll be limited at the top end, we tend to see 0.3-4bar increase over 4500rpm with the ITG setup... without the ECU just pulls load out towards the top of the rev range! Well worth it! On a completely separate note looking forward to seeing you a Saul's!

    32 was showing block 1 - 0% and block 2 - 1.4% yesterday afternoon following a good run out. Factory specs are within +/-12%

    On more suggestion.

    May be, like APR Stage III kit, Itg should try to use a one piece pipe near the MAF instead of two pipes.

    I think they wanted to, but due to the pressure drops they wanted to maintain the thickest possible gauge piping for as far as possible to maximise turbo spooling capability. It was critical to ensure there was the right diameter / length of piping to ensure the MAF was posting the correct figures back to the ECU to ensure optimum running. This turned out to be the most suitable solution for overall performance, but was a bit of a cosmetic challenge.

    Problem with battery in boot is if it fails/problematic/flat then you have problem to get it out, so have to climb through etc to get into boot, so slightly inconvenient & tbh pain in butt overall as I was messing with battery & kept forgetting boot is electrically controlled so had to keep reconnecting battery, lol, hey was raining so couldnt leave open, so for me I'd rather leave where is.

    You're right it would be a P-I-T-A, and as such I guess it's only really recommended for the likes of Andy Oram or Jonny Cocker where they are fitting BT's and running 450bhp+ without compromises.

    Haven't heard much from Andy Oram lately since his engine woes, I hope he's OK, and the car is on the way to being fixed. Poor chap, such a shame as he'd not cut a corner.

    I also hope it's all gone OK,but building and running high boost engines is not for the faint-hearted or those without deep pockets.

    I benefited from having an engine builder with years of experience in building rallycross engines with over 600bhp,and thus knew all of the pitfalls and weak spots in that particular engine.

    You need to pay a lot of attention to cooling,and also to things like crank and head breathing systems to avoid ingesting oil vapour and getting detonation as a result.

    Anyway...enough of that.

    Warren....seems as if your problems were very similar to mine,and I hope you enjoy the cure!

    RRP will be 300, but normally you wouldn't get free fitting.

    As they needed to finalise the connections, measurements for the heat shield and filter head sizes for the S3 I got my fitting for free. Before it enters anyone's head that I am doing ITG a goodwill gesture for getting a FREE filter, I have an invoice to prove I have paid for this item. 95% of the development work was already done, so it was a check & fit job in the S3. Yes I got a gesture discount for donoring the car, but most of the donkeywork was conducted on Revo's Leon, a Golf (on Golf GTi Mk5 forum - Steve), and an Octavia. I happened to speak to Carl at Revo the other day and heard they were looking for an S3 template.

    The good news is that I can ethically put my hand on my heart having paid a majority percentage of RRP and say it was money well spent. It would be much harder to review the product objectively had it been free as I'd have felt an obligation to be kind.

    As it happens, and fortunately for me, its a revelation in performance and sound. I took my brother in law out in it last night and his immediate response was 'f**k me, it sounds and goes like a rally car'! He's into his modified cars, and has followed the path of upgrade on this car closely; he said this upgrade has taken the car into a different space as it has shed the overly-polite S3 tendencies and added some real attitude to the mix.

    Every day I love it more, and with the new BKR7EIX cooler spark plugs I fitted on Friday night she feels a treat (for now!). I'll enjoy it whilst it lasts. This intake is not really for the faint hearted as it never really lets you forget its there. There is always a faint resonance of rushing air in metal piping even at low gears, but the most impressive part still is the rate at which the turbo can spool up. It's transformed the car as it's no longer breathing through a letterbox. Andy ITG said you have to give a turbo unrestricted breathing, and it appears this is the case. They will breathe as hard as they are allowed, and by opening it's lungs its a different beast. When opening the bonnet you can also feel a drop in ambient temps to the sealed off side (noticeably colder). I just need to get some insulation jacket from Agriemach and it will be job done.

    Only downer is I have a leaking tyre valve to replace on Tuesday :-(

    Top write up Warren, I've been following Steves thread on the mk5 too. Is air ducted to the filter from anywhere? When do you think the kit will be on the open market and do you have any contact details for a supplier or can we buy direct? Sorry for all the questions

    About 3 weeks to a month to become fully available.

    Direct purchase from ITG for now, and contact Andy Jackson on +44(0)24 7630 5386.

    I was thinking of fitting some air ducting from the front nearside fog light enclosure to the bottom of the filter, but not until I get the bumper off when I go to fit the spray bar. That said I question how much it will add to the equation as the flow path is pretty reasonable. I need to get under the car to look at what the air does when it gets through the bumper intakes.

    warren, ive been told your running ITG + revised oe dv.. just wanted to know something.. with this set up are you getting a nice chtter sound when letting off power? just like decked's S3.. there is a thread at the moment called something like "recirc valve" there is a video in there of the noise im talkin about..

    also another thought i had... looking at jonnycs and madalexs threads they have the braille lightweight smaller batteries.. if you went with one of these do you reckon ITG could use one of the better filters? wothout relocating? although it prob wouldnt make much difference havin one of them... im sure you set up is more than enough!!

    The compromise
    In a perfect world, as Andy is passionate about quality, he would have loved me to have either relocated the battery, or replaced it with a slim line one (Audi TT's have this privilege bestowed upon them from factory. If so we could have fitted one of these babies:

    However, this is a compromise from a cost and convenience perspective I could not commit to. Big turbo cars would benefit from considering this as the filter would be able to flow well in excess of 400bhp due to its increased size. The one in the pictures is good for over 360bhp which mirrors closely with Revo's stage 2+ pack.
    This was not to be, so a conventional barrel filter was fitted with a surface area which closely mirrors that of an OEM paper filter. Due to the maths, the surface area of the filter can significantly increase/decrease the capacity to produce BHP in turbocharged cars, and although Andy did furnish me with the equation for this for the ITG foam and how it's BHP capabilities per cm2 area change I have to profess I have forgotten them :doh:

    Andy recommended this, but when you are spending upwards of 600 for a CAI it gets pricey. Yes there would be additional gains, but enough????

    Another Question

    Did any of the fog light panels have to be removed or modified for this intake? I've been having a look on my S3 and I can't see where all the air would be coming from?

    Not to date. The air from the near side fog light comes straight up into the engine bay and into the filter as the arches don't have arch liners (like the old Audi TT). Yes you could plum in directional hose, but it wouldn't add much to the mix.

    There is also air ingress around the headlight and the grille into the critical areas, and although its not ideal, only a headlight removal or bonnet scoope could improve things much (or the battery change mentioned above). It's a vast improvement over OEM, but as with anything there is always scope. Thermal wrapping is next.

    It is, the kits were off for some coating to be put on the aluminium pipework to help with heat resistance.

    May be worth calling Andy Jackson at ITG, as I believe they now have a distributor in the UK.

    Surely the production kit won't use just a piece of foam as a heat shield?

    A lot of the ITG kits look really slick, but that looks like it was put together using a box of universal pipes.

    On both my and Revo's car putting the piece of foam in serves 2 purposes. Firstly it seems to equalise the pressure either side of the foam, as the air in the section around the filter head strangely seems cooler than the air within the bay. I didn't initially believe it could, and I can't explain the physics, it just seems to work.

    In essence it was, but pipes that were given a considered diameter to ensure MAF compliance and air flow maximisation. It's no looker due to the **** configuration / lack of space under the A3 bonnet. There were very few other ways to solve the issue, and many were supposedly considered. This method was a compromise (they really wanted to move the battery), but I couldn't go for that. TBH once the bonnet is shut it can look like what it wants as long as it works.

    Not doubting the effectiveness of the foam heat shield, it just seems a very cheap and cheerful solution rather than a properly engineered heat shield that many kits use.

    I'm sure it works ok, but with a bit more cash spent on tooling, I'm sure a much tidier solution would have been possible. I'd expect better for 300.

    As F1 teams generally design the intakes themselves, any filter company will effectively be producing a filter to suit the team's designs. ITG play on supplying Renault F1 all the time, but it doesn't reassure me they are the best qualified people to develop a CAI kit.
