Could someone please let me know the part numbers for the S3 arch Liner vent and the TT arch Liner vent.

I have checked the forum to find info on this mod and I have found two topics that mentioned this and they have advised that the S3 vent is slightly larger than the TT vent, is this true?

I have thought about doing a DIY version, but I'm not to sure which way to perform this mod.

I have found the American Part number for the TT arch Liner, but I would prefer the S3 if it is bigger.

I think this mod would work well on my car as I have the up rated Forge Intercooler and need better air flow.

This are the main sites that I have found to help but if you have better please let me know

I have the uprated forge smic aswell but I was planning on doing the cut and hairdryer mod :)

I was thinking of doing it this way but I'm not to sure what it will look like and whether it will be good enough to protect the intercooler from water ( i supose that will not cause a problem, more of a plus than a problem) and dirt off the road.

Most people just cut the vent shapes into their existing liner and then heat the plastic and bend slats into it.  If you drill holes, cut sections out of teh liner, you are allowing a lot of muck and water into the arch. There is no proven gain from doing this mod at all, but the laws of physics say it should help.

I have often wondered about doing this mod too,....any info would be appreciated.

As for the benefit, I would of thought that the increased air flow over the intercooler would be very beneficial in terms of generating slightly more power (the more air and colder it is the better).

I would also think it would greatly improve the flow of air over the intercooler as it would have somewhere to go rather than bouncing back from the liner??

I dunno, just theorising really.

aye that's the idea of it - the way I look at it is that it can't do any harm - apart from maybe let a bit of muck in in bad weather but I'm gonna do it anyway.

If nobody knows the part numbers or they are too nasty to tell me - then I'm just gonna find some kind of plastic vent from B&Q and do a DIY that way - from the pics they don't look too special!

That will look totally naff. For the sake of all VW Golfs son't do it. Just modify the vents you have.

I don't get you mate - what vents do I already have!!?? Do you mean modify my existing arch liner - with the hairdyer / dremel technique?

I'm sure there'll be square black plastic vents in hardware shops that are exactly the same style as the S3 / TT ones or similar? I wouldn't do it if they looked shat!!

If I can't find anything I'll probs cut my existing liner.

From homebase you can get shower ones with a light in. It could be a "puddle light" upgrade too!!

Curtains are available at IKEA for the back window!!!

I sorted myself with a vent today at B&Q - it's great and has a built in fan

I've fed it direct from the battery via a little switch next to my hazards which I need to turn on when I start the car. That means not only am I letting air over the intercooler but I'm circulating it around as well. It's a bit noisy mind but you have to take the rough with the smooth - and I've noticed much smoother throttle response and the car is defo quicker

Do it!

cheers for that mate - I think I'll get myself a TT liner this weekend and carve it up.

Incidentally while I'm at the Audi dealers (or will VW stock Audi parts!?) I might as well get an S3 lower strut brace and the fixings - part numer for that anyone!!?????

Get the S3 liner, it has a bigger sized vent than the TT version. I got mine from VAG parts, and it cost about ?15. I fitted it in about 1hr, riveted instead of screwed. Looks good, the benefits are not seewn, but in this weather it must have some benefit.
