i'm looking to get a cold air intake for my bimmer. is there going to be noticeable difference in power or gas milage? or is there even a point in getting it?
x2. There may be an improvement in airflow by using a Euro airbox (at least this was true on E30 3ers), but you'll typically just end up pulling more dirt into your engine, along with more noise. Save up for a chip or suspension upgrades, depending on your goal.
