Hi I hope this isn't a duplicate question, I tried to search the forum for answers

My question is, for the OEM BMW Performance Intake, is the filter meant to be replaced or is it cleanable?

If its a cleanable filter do I just hose it down with water?

Cleanable. Purchase a K & N Recharge kit. If you like you can replace it though. You should also clean your MAF sensor more often since the perf intake filter is an oiled one.

I dont think Perf intake is an oiled filter... its dry version from all that iread

It is, it comes wrapped in plastic to keep the oil contained. My hands got pretty slippery after I installed it in my filter box. Link below has more info

That is correct. All BMW Intake Performance Filters are oiled filters (k&n recharge kit can be used to refill)

Would the PI be more beneficial with an AFE dry? Not like I would ever shell out 700+ on an intake for this car but just curious.

no no no no no dont even think about touching it with a towel, CRC mass air flow cleaner from autozone or advanced is the only thing. Mess with the MAF sensor at your own risk lol.

Just pick up some cleaner like Benzo pointed out. There's some DIY vids on YouTube too, just search 'E90 BMW MAF how to clean' or something similar, very straightforward. Hardest part is taking the sensor out!

I think that just goes back to the age old filter argument of oiled vs non oiled vs paper. Since the PI retains the rear housing and uses the same size filter realistically you can use whatever you want. Will it make a difference? Probably nothing noticeable. When I added my PI I noticed more low end torque and faster revs (barely noticeable, but it did make the car more responsive and more fun to drive!) Where the PI really shines is over 100km (60mph) it's a monster at that point, but since the air is coming in so quick I really doubt filter choice would make any noticeable difference except the whole oil getting on the MAF thing.
