NOT more power but better acceleration and response! Later will do a catch can so all that gunk won't enter the engine and get clean air.
Don't worry about the negativity, or un-motivational responses, It's your car, your money, so do what ever you want with it!! 
By the way! Great work on your engine!! |
I don't think anyone is being negative, you're taking it the wrong way. Do a search and you will find some pretty lengthy threads about this subject with links to other BMW sites as well. The consensus is that nothing beats the stock BMW air filter for air flow, look at it this way, at least they finally got something right on this damn truck....LOL!!!!!!
