Just hard to believe 8 whp which is close to going catless (well half) which seems hard to believe
I think this mod is really more for the sound than the power gain. Their full intake for the e46 M3 sounds insane. One of the best sounding cars I have heard. I am tempted to go buy an e46 M3 and put their intake on it just because I liked the sound so much.
