This is the intake as seen on Ro_ja_Boy's. I'm curious to see if this design is effective. It looks like it is pulling cold air out of the area in the fender with a reserve before and after the filter. The Kevlar CF construction is to insulate the intake air from the engine. A design that makes sense, however, tt would seem the shapes of the two chambers would cause turbulence in the intake air. I assume GruppeM must have done some research before producing the intake. Can anyone with the background explain to me the dynamics of this intake design?

 

I think it has something to do with throttle response and pressure so that the motor does has to do less work sucking the air in...

 

I think it is all about volume and fully enveloping the filter with air equally on all sides.

have to say that the J's and ASM intakes still win the competition for me in terms of being the most efficient design,

same principles as the M's just slight better executed, which is what all good Tuning parts are really.

 

I really love the GruppeM!
Were can i buy one?

 

Right here TommieB ... GruppeM

 

The quality is definatly there. Just get ready to trade your first born for it.

 

Yeah, you really gotta buy that because you want it and for no other reason. Absolutely not for the best horsepower per dollar naturally aspirated.
