I'm new to the forum, but better late than never. I own a box stock E-46 M3.
It's steel grey with grey interior and manual shift. The only mod so far is tinted windows!
Well, after two years of joyful ownership, I'm starting to get the urge to tweak the car, and of course that means performance items.
I've been on the BMC website and looked over their carbon performance airbox.
It looks good, but it's expensive, $855. I like it because it uses factory ducting, no inhalation of hot underhood air here.
Anyone have experience with this device? How about other mods? I'd like to drop the car a bit, but I do not want to make the ride worse than it already is.
All comments greatly welcomed,
