GruppeM Air Intake


Recommended Posts

I've seen some adds and write ups mentioning the GruppeM air intake. Anyone have any previous experience with these items? Is there a supplier in the US and what the pricing might be for the GT3? They seem to be a quality piece as they seem to be used in a few race applications. I might be considering putting one on my GT3 depending on all of the above. Tnx

Very attractive piece. Considered it for a while, but ended up going with a BMC F1 free flow panel replacement for the stock airbox. To get the greatest perfromance advantage, the exhaust and intake should be done together. Do a free-er flowing exhaust with less back pressure, then add high flow intake via a perfromance filter or airbox combo like the GruppeM. I asked them for some performance data and they were either unwilling or unable to provide it. They never called me back. Guess it's worth it to give them a call back...With my new exhaust and BMC filter any performance advantages with the Gruppe would be negligible at best. My new filter $125.00 vs. Gruppe setup $1,250. Does'nt sound worth it unless you like the looks(I do), it really dresses up the engine compartment. I may do it down the road if I am board and have nothing else to do on the car which is pretty much the point I'm at now.
