Gruppe M Replica VS authentic. Anyone know the difference?
Just like the thread says... I have the opportunity to pick up a replica intake from another forum member but am a little worried to pull the trigger on this one. I know that it is not an enclosed box but does isolate itself from the rest of the engine.
I also know that the authentic intake system is made out of Kevlar/CF so how does this compare to the replica intakes out there in preventing hot air suction?
