Shielded induction kit

my mate had an induction kit on his mk4 golf gti that had a nice bent stainless pipe that put the filter sort of behind where the fog light would be.

Would this be a better solution?
Do they do one?

I think i seen one on a TT, would be colder there surely.

With mine,i have just smoothed the oe airbox and gave it a cold air feed from the front of the bumper!..
 
s3 nattie have you got any pics with the actual airbox top on instead of just the airbox cover as thats too open for me, want my fully sealed if i do it.
 
If people are keeping the airbox...what exactly is wrong with a correctly fitting panel filter?
I don't get what a cone is supposed to give...especially one that's small enough to fit, and likely to have a smaller surface area!
 
No disrespect but cone filters are a waste of time, the engine bay gets far to hot, different tuning companies have said the same thing...fair play if you want to spruce your engine bay up but performance is going to suffer...
 
Looked like nattie could fit a larger cone in tbh, if i did do it i would say the twin cone that green cotton offer.
Totally agree leggy, thats why if i do fit a cone id want it closed off from the engine bay with a nice cold feed to it.
 
A number of companies produce OEM oiled cotton panel filters, are these any improvement on the paper jobs?

The original paper jobbies are fine, though I changed my to a green cotton panel filter, don't think there's any performance gains, just a nicer induction noise...
 
a guy on another board recently dyno tested difference between a paper filter and a "performance" one. no gain at all.

one annoying thing about "performance" filters is the cleaning and oiling cost

just get a paper one

Has anyone managed to get a 4" ducting pipe lown to the lower bumper while still retaining the original passenger smic? If so, please post pics.

I don't think it's possible.
It's a hell of a squeeze - including moving the battery tray over a bit and lots of swearing - to get it down with the SMIS removed...there is just no room with a SMIC in place.

A 4" duct is a big diameter!...not only to get through past the battery/light, but to find a home for behind the bumper - impossible I'd say with the SMIC in place, especially as you really want the pick up to be in the area where you pick up a few "/wg of positive pressure, ie, right where Audi put the SMIC.
 
To be honest with you guys I had the filter for penuts so was going to give it a try just to see really.

I thought the filter was bit small but havent noticed any decrease in power but it does run much better in the evenings or on a chilly day, havent had any heat soak yet.

I havent got any pics of when it was installed completely inside the box but all you relly need is a little bit of piping or a steel cone so it fits inside comfortably.
 
just a quick one is the S3 airbox and cold air feeds the same size as a A3 1.8ts no quattro
 
i was looking under bonnet on my a3 1.8t quottro can you not put like 4 5to7mm spacers & longer bolts to match on rear of bonnet to lift it up to get rid of extra heat i no some peeps do this on honda civics etc.this would help with standard air box set up or induction kits would it not? would prob only be any good in dry weather but thats when most go out for a blast & go to meets etc.i may try this out

Do you mean where they lift the rear of the bonnet? I thought of this but don't like the look of it myself. I am now looking in to cryo kits to see if they can cool the air and fuel(more cuz I wanna know if I can do it, how hard can it be?!).
 
I wouldn't worry too much about spending a fortune trying to reduce the heat under the bonnet. On a A3 turbo or the S3 its been proven that a £300 fmic will do the job and on a non turbo car the temps wont effect the performance as much.

I think the best thing to do is to have a closed air filter with a nice big intake pipe that is positioned in the front bumper to create as much of a ram effect as you can.

yea thats what i mean should work quite well in summer but in winter would need to lower or the heater prob wouldnt work very well.& it would not cost much to do a few spacers & bolts job done.i am lookin into getting a ths motosport intercooler pipe which will help more air go in & mod inner wheel arch to let heat get out better.as on standard set up air does not flow very well past intercooler & will hit iner wheel arch & circulate around back of intercooler so if i can help it get out it will run cooler & you have saved some money buying a fmic kit.i no its not the best fix but times are hard & i like playing with tuning my car as well as my bikes.
 
erm, i dont think you have saved anything at all, your mod is not going to do anything anywhere near what an FMIC will do..... the air being sucked in is from behind the bonnet and not from the front.... this isnt the most effective way to get cold air in from the start....remember an FMIC will have the full force of the cold air your car is aimed at, you simply cannot imitate it by 'lifting' the rear of your bonnet

i no this the bonnet lifting is for getting rid of hot air not trying to suck in cooled air.& not every body can afford to get a fmic.i am looking to get a better air flow past the standard intercooler & probally look into air flow to inner panel which feeds the standard air box feed.i like a challange & enjoy solving tuning probs while trying to keep a small budget.you can gain power if you no how to do the little things that count no point building a fast motor if it cant flow in & out fast enuf

na fair point, worth considering though that a hell of a lot of people who know what they are doing have tinkered with this car for years....results of which can be found by searching, certain members are more prolific than others..... not saying dont try, but logic tells me that this car isnt like a mk1 Escort, you have to throw money at it to get anything worth while..... good luck with what ever you do with it, though i fear the problem is more than just getting air flowing through....the IC's are in the wrong position which is why an FMIC does so much of a better job...thats just to start with, loads have researched the cold air feed coming through the bumper....which would obviously be the best spot for it, modifying into the arch will not provide what you require as the 4" feed doesnt give that much benefit in itself.... im sure if im wrong about any of the above someone will pipe up

not saying you shouldnt try, you have to look at whats been covered time and time again to assess whether your wasting your time
 
What about bonnet vents? If you are trying to get colder air to an IC surely this'd be the best option? Look at Scoobs and Evos and their set ups.
 
Bonnet vents wont do anything for the IC's, theyll just allow cooler air in/hot air out depending where placed.
 
the IC's are hidden bang in front of the wheel liners....you arent gonna get much more air into that spot because they are isolated, yes i would imagine vents or lifting would help pull more air out...but essentially all your doing with an FMIC is making better use of the power you have as opposed to increasing performance.... doing what you say would not yield more than 20% decrease in temps if your lucky IMO.....

im afraid FMIC is a means to an end, do the FMIC and then you can fit a better CAIntake..... it will be a miracle mimicking the FMIC's positives based upon whats already been done by people willing to throw money at this car
 
Getting cold air into the engine bay and getting cold air into the engine are two seperate things. Having lower temps in and around the smics and the airbox will help very very slightly but to feed the engine properly you cant beat a fmic and a larger intake for the airbox.

Also bare in mind that the smics are fine on a standards or big turbo S3, its only on a remapped K04 that the heatsoak issue really come into play.
 
Wow, been researching old posts about intake since I was planning to get a K&N 57i kit next monday... But now I have serious doubts!!!
I cant lie, I would love to have a deeper sound and louder blow off from my forge "splitter" valve, but I also don't want to compromise the performance...
The general recommendation here is to stick with the air box but, should I add secondary cold air ducts? drill the bottom and smooth the inside??? (good example: VolksDevil Vw Forum • Airbox smoothing and cold air feed.MK4 Golf/Audi A3/TT ,Leon)
this is what I'm planning now!

Cheers!
