i understand that the market for the C63 is not very big but i think this setup is a little overpriced for what you actually get out of it . if someone is looking for a performance gain , i think i would go a different route

$4290 O_o for what ?

for all the carbon fiber

there must be a shortage now

Looks like another Gruppe-M replica including the airboxes. $4300

it's basically for looks only

i paid less for my hood , trunk , spoiler , front lip and rear diffuser and still have enough left to fill up the tank a few times

Wayyy to expensive.

:r olf:

i just seen this one What a deal !!!!!!

Come on Propain, I know you want to buy it.

Is .05 worth 4K?


I still want to get the Gruppe Replica for $1100. Its hard for me to even justify THAT.

That is a good deal. But they are worthless from what I hear.

The Renntech airbox Mike (Petro) let me borrow at the track (thanks dude) seems to drop me about .05. I need more data though because the humidity also dropped at that time.

I hear the Gruppe shows some results.

Aren't all of these intakes for looks anyway? Like most other CF parts for our cars. It's like the new fad for decals haha

Opinions vary.

Propain: Renntech + GruppeM?

i am certain to get the most out of airboxes you need to follow up with the typical things , More air needs more fuel and needs less restrictive exhaust.

How they test them is beyond me ???? Maybe the power claims are from the charcoals being deleted ????

No just the Renntech Mike let me try out.

I am leaning toward the Gruppe replica because I hear good things and the price is better than the Renntech.


As to the other link I didn't know the C63 could use scoops...

i dont think the e63 scoops would work on the c63 front air dams . i just threw it in there to get rid of them

Ahhh, I didn't realize this was your listing.

gruppe replica link please? i couldnt find a link on the net or forum with a search

Nothing beats ROW airboxes. I have them stock and fitting a Renntech intake hasn't done a thing for performance gains.

Looks cool though!

This thing looks like pigs A$#%

Are these joking??

What happened to Renntech's front scoop setup? Weren't they going to offer it soon?

Renntech airbox +1

The upcoming Renntech kit looks promising. Im sure it too will be $4k
