S3 Spark Plugs - Stage 2+

[S3RYE]

Hi All,

As you know been running stage 2+ for around 10,000 miles.

When it was taken from stage 1 to 2+ i had the plugs and coilpacks changed over to fresh OEM ones as reccomended by AMD Essex. The ones in there were fecked and gave up the minute it went 2+. Now i had previously seen a lot of talk about colder Iridium plugs but AMD said there was no need (not sure why)

My car has developed a major misfire/stutter and im thinkin its got to be the plugs again as it feels exactly how i did last time they went. I have two questions do i go for another stock set or colder ones?

Also who has the OEM plug part nos so i can get them from Euro car oarts or the like?? or if you have a different suggestion of plug which ones?

Thanks in advance and quick helped will be much appreciated!!

phils a top man! sorted me out a few times. Thing is i need the fast like today and by the time i drive over to west to meet phil i may as well pay more and get them local! Will i need new coilpacks too?! they were done 10k ago?

cheers though bro!

Have you got vagcom if so you could do some data logging to see what coilpacks need replacing .
I'f not and it was me I would change all four to be on the safe side.

No vagcom! will the coilpacks needs replacing though after 10k?

Coilpacks shouldn't need replacing.

Take the plugs out and clean them GENTLY with a bit of electrical contact cleaner and an old toothbrush. Should keep you going until new ones arrive if it's just a bit of plug veneering.

One of the usual suspects did data logging with plugs and Iridium 7's gave better general running conditions than OEM plugs. Only issue you will suffer is if you do lots of short journeys they may cack up quicker.

In principle I agree with AmD that OEM should be fine, but the 6 temperature plugs don't seem to last any better. Supposedly VAG group are running a revised plug in these engines now, so may just be worth trying those from main dealer; about £40.

Thanks War!

Ill call them now, see if i can collect a set tonight. Get them installed tomorrow!

 

[S3RYE]

could someone give me the part no for the S3 plugs? its a MY09. Audi want£53.52 inc vat for 4x plugs is that te right sort of money? or much cheaper at Euro car parts?

 

[S3RYE]

thanks for all the answers guys! NOOOOOOOOOOOOOOOOT!

youll be glad to know its all sorted.

New plugs from Audi (got *** raped £53)

Misfire/hesitation = GONE!

oh and i threw the boxes away without looking at the part no

 

[S.]

yes..but for how long?

 

[S3RYE]

hopefully another 10k! although it wiull be in for service in 5k haldex change, oil service an all that. So will prob have another new set then. Im not being funny but for £40-50 its worht changing them often. I think the fact i do lots of small journeys where the car doesn't get fully warmed isn't helping!

Interesting.....the advice I've had from both AMD and VWRacing is to use stock plugs,and change every 5000 miles or so.
My car has been at Stg3 for around 12 000 miles,and Stg2+ for nearly 20 000 miles before that,with no problems related to the plugs.....the only misfire issues we had were down to the stock intake strangling the airflow,and once that was removed(at 2+),there have been no further problems.

strange, my car munches plugs like a crack whore

 

[jsws3]

My mrs does 8 miles a day from home to work and we have never had any coils or plugs go down on us and if been at stage 2+ for about a year .

 

[S3RYE]

im obviously different to you all.. maybe i drive harder than your mrs? or im just an unlucky pr1ck with a lemon

Who knows.....it may be individual cars and settings,and a host of other things,but as I said,mine has behaved itself very well,and there are no misfires if the plugs are changed every 5 000 miles or so.
I've certainly found it easy to tell when a set are on the way out,as it does develop a progressive softening and small misfire under full throttle when they're really done......but the OEM ones are fine with 2 bar peak boost......WMI and more power on the way.

its probably cause i left it so long to change them, a pure oversight! it was around 11k! so there your answer probs! it went exactly how you said! softened, then misfire!

cheers Al!

nice to see your taking your car to the next step! have to get a run out in this sometime before you let it go!

I left a set for 10 000 miles and found exactly this problem......just a worsening misfire and softening performance,which a new set cured.
Mine is almost ready after having a bottom end build(pistons and rods) as well as a USP Motorsports auxiliary fuel pump,turbo heat jacket,few BSH bits,and an AEM water injection kit.....a friend of mine on another forum has a mate getting over 530bhp on this sort of setup,so my fingers are crossed.

Any time you can get to one of AMD's Open Days,or perhaps the Inters next year.....or something I can get to,you'd be more than welcome.
