Installed the Gruppe M intake last night, along with the red out tails. I didn't realize my BMC filter had gotten so dirty and on top of that, the rubber surround was breaking apart. There were large pieces of rubber between the BMW filter and the BMW filter on the top portion of the airbox, very glad that additional filter was there! Replaced the rubber trim piece on the Gruppe M and shined up the carbon, looks good as new.
The scream of the Gruppe M is nice, and going from a dirty filter + second filter to the single K&N filter did feel like it did the motor some good. Did some pulls with a friend's ISF with intake and catback exhaust, though, and still couldn't hold a flame to him once I hit 3rd.
