Gruppe M intake questions

i can tell you 2 out of three

i got a 03 m3. i got mine in a group buy for 1,150 i think.
suppose to give you well for my car 12 to 15 hp. and i think puting it in a m3 is a little easyer. than in a 3 series i think you have to cut out a piece if i am not mistaken.

It took me about an hour.

Not very hard, just print out the Instructions from Renn-Sport.

I got mine in a group buy $520 I think shipped

The install is a cake if you've done any intake install before.
www.renn-sport.net and watch for the group buys.
1,000,000hp increase.
