Drop in filter vs Air intake?
So I currently have a BMC drop in filter in my 2008 e92 m3. I was considering the AFE stage 2 carbon fibre elbow intake. Although after reading several threads I have heard of some rattling noise issues and a few others.
My question is....is it really worth spending this much money for an air intake? I read that majority of the gains come from the air filter primarily (especially for earlier models m3s like mine because of the charcoal filter), and I feel like this would mainly be a cosmetic mod. After reading more and more I can't really justify buying an air intake. Also my exhaust is quite loud so I am not sure if I will be able to hear a difference in cabin. Should I just stick with my drop in filter I recently purchased and just call it a day? |

My AFE oiled drop in filter was worth 4.5rwhp, the AFE Stg. 2 oiled CAI I got 10.8rwhp. I didn't feel any difference at all, but the sound did improve as the CF elbow let a lot of the harmonics out vs. the plastic.
