I hear Highline Tuning is coming out with a M3 intake to be premiered at Bimmerfest.
I know the M3 intake won't fit our cars but their intake looks pretty awesome. The pictures are not up yet at www.highlinetuning.com
you can contact them at firstname.lastname@example.org
, ask for Mugu. I'm gonna contact them and see if they are going to make one for the E90's.
Regarding the original post: That carbon fiber intake on ebay is made in Taiwan. The heatshield is generic and not specifically made for the E90. That generic intake sells for about $24 in Taiwan.
