Authentic Gruppe-M intake for E90. The set is complete with all hardware, etc. I got the intake from Samir at Technik, it came off their project car (the car that was recently for sale on eBay):
Intake has approx 2K miles on it and is in excellent shape. I had it installed for a couple weeks but decided it was a bit much for me. The car sounded great and felt more responsive but I think I like the quieter stock setup better.
Anyway Samir gave me a great price. I'm not looking to make (or loose) money - just want someone else to enjoy it. PM me for price.
