The AFE Magnum Force Pro Dry S Cold Air Intake Systems for the E90 / E92 / E93 / E82 / E88 N52 and N53 3.0L Equipped BMWs. This AFE Airbox System produced max gains of 12 hp and 16 lbs.-ft. torque in testing at AFE and outflow the factory intake by 56%.
I want to start off by saying the intake is of great quality and I did feel a noticeable difference but that's where the good things end. It's a absolute pain to install, especially at the throttle body, the maf sensor barely and by barely I mean I had to really pull every cm it had to give to connect it. The lid didn't line up properly with the box, the air filter that gets connected to the box also didn't like up perfectly, let's just say a few screws don't exactly line up and I had to improve to screw them in. I expect better product fitment with what you pay for this product.
Install was fairly simple. You do need to wipe away oily residue on inside of connecting hoses from throttle body and intake. Otherwise there will be no friction and the hoses wont hold. But other than that the system fit fairly well. Definitely added some HP. Sounds really good as well. No software upgrade required. I would rate the system an 8/10 .
