I really like this

I own BMW 07 328xi.It big change from stock to air intake perform. I love the sound so good, but the problem is ( why afepower make it little bit shot)?.(Connect from engin) It 1/2" or 1" short and clamp too small.It is so slippery and it will slice off 500 or 600miles. I check mind every week. I hope afepower can fix what they did wrong. I say because I like this air intake. Thank you

E90 BMW 330i

Autoanything produced the best price around for the intake. Delivery was as expected (dropshipped). The carbon look lid is attractive when you open the hood. Sealed design keeps intake temps lower than open designs. Utilizes the BMW factory air supply ports. Instructions provided were a bit bass ackwards, but you will figure it out as you go. Sounds good, not too loud under normal operation, but growls under WOT.

aFe Stage 2 Si Air Intake System with Matte Black Housing Cover

Overall, I am pleased with the intake system. I currently live in Chicago and installed this modification in 40 degree weather. I previously had the Stage 2 Magnum Force Air Intake System and it was good, but I like this better because I feel the extra power from the car. Installation was simple as long as you follow directions.

aFe intake review

As far as aftermarket intakes go for the e90 BMW's, the fully enclosed afe stage 2 si intake is definitely one of the best options. its a bit pricier but the fully enclosed design ensures that no hot air will be sucked in. the sound is amazing as well. install is very easy!
