Nice stats, one missing though....how much is it?!!!

Brand new from Japan your looking at around £1100.

Second hand anywhere between £500-£800.

But I guess you know that right

One awesome looking bit of kit but is it worth the money performance wise over a simple panel filter?

Doubt it but I'd like to see a KN panel filter stats too. Think the best gain of the Gruppe is the colder air you'll gain.

Had no clue buddy! I'm new to the RS4 game and never googled it because I know i'd be way too tempted!

We're going to dyno before and after on panel filters with our demo.

K&N and Pipercross - be a while yet but interesting reading no doubt when we do it.

I will be interested as I have just bought a K&N from you guys lol (revolution).

Does it still use a flap?

If it's a single cold air intake this would be very good. The RS4 has pretty aggressive timing retardation when the intake air is warm.

No flap, the airbox is totally removed (thus removing the flap) in the kit there is a rubber plug that is used to block the vacuum line. The secondary air injection pipe gets a small air filter too (Crank case breather filter).

good choice

Hi Sonny
re gruppe M - there were a few posts about them causing tickover problems (i think it was that).
Has yours been okay?

Were looking into a similar (but cheaper) alternative and proving difficult to get the carbon intake done in small volumes at a decent price - just want to make sure it runs fine before we go further.

Hiya Glenn. only thing I have experienced is a drop in revs every say 60 seconds or so, the needle will drop slightly then idle again, but its not a problem. I put it down to the car not being remapped to the GruppeM filter like mine is, so I should really have a fresh remap uploaded. When I had my old GruppeM on the car I never experienced this, may be due to the APS remap I had?

Now you have mentioned it, it has made me think. can you post a link to the tick over problems?

cheers sonny

i looked and couldnt find it - anyone alse help?

Would a GruppeM not also benefit from a vorsteiner vented hood?

Yes, but it would, but I dont like them as I like it too look OEM from the outside.

Not sure if it would benefit, doesn't it have a duct ?

As above tho, stock looks best IMO
