Dinan just released cold air intake for E46 M3 but I don't think I can afford to mod my car! $2400 just for the intake and to truly get a use out of it you need a stage 2 software which costs $900! What in the world?!?!?! I need a better paying job :( or I need tech stocks to pick up once again. Or.. anyone wanna be a sugar mama for me (read my car)?
