I think I'm going to remove them. I don't see how it could hurt. The K&N decision I'm a little more skeptical about given the mixed results on back to back dyno runs I've found out there. Seems like for some cars it helps a little, others hurts a little, some no change. I'd love to see back to back dyno runs on the f90.

I just left a meet where the owner of MSR brought his M5.... Wow! That thing is a beast, sounds amazing with his intake/exhaust setup. I had an msr intake in my last one..... Can't wait to get one for the F90.

Doing this mod as I type this. Driver's side done, very straightforward mod. Thanks for writing this up. We'll see if i can perceive any difference in sound.

One thing I noticed after doing this, is you can smell the exhaust of cars in front of you if they floor it for instance.
Does our climate system have a charcoal filter for odour removal ? |

Great job with this quick tutorial; took no more than 20 minutes from start to finish (and that was with struggling to get my stubby hands under the air box cover..)

Thx AGS. Did this last night. Pulled the charcoal filters and also dropped in the BMC's. Feel so accomplished turning the wrenches myself.

Just wanted to thank you for such an awesome write-up! Removed my charcoal filters and swapped in BMC air filters tonight. Super easy with your guide!

Agreed on the thanks OP! Super easy diy pulled the charcoal filters and added BMC. May sound slightly better but no real noticeable gains. Either way good to know those cheap charcoal filters are out of the way!

A definite improvement in turbo sound and BOV sound!
Also wanted to note that the rear bolts on the braces are 18mm and fronts are 16mm so no one has to spend time checking |

Does anyone know what the purpose of the gray felt on the OE filters is for?

Thank you for the write up on this. I've been wanting to change the filters and been wondering if it would increase turbo and BOV sounds. Looks like it does from (thanks devondragon). Just curious is there a difference between BMC filters and K&N? I've always used K&N.

Man. I have to say this was alot more work than I thought. While I really appreciate the torx bolt revision, you have to really muscle out that stupid air box.
I can actually hear the turbos winding up now, so well worth the sweat. |

Any sound clips from these guys? I'm sure the stock air box flows really well with the filter change. I want some performance but ready looking for sound. Weighing the options of intakes vs just doing this which will probably flow better then open filters in the hot bay. Thoughts?
