Hey,

I had a really hard time finding out replacement parts (both OEM and aftermarket) for the engine air filter and the cabin air filter as Subaru does not provide part numbers on these OEM parts and the online databases for the 2008 WRX are wrong and have costed me $$$ on incorrect filter sizes. The owner's manual states to replace the engine air filter every 30,000 miles, and the cabin air filter every 7,500 miles or every 12 months - whichever comes first. I'm just posting the info so that people don't make the same mistakes I made and for easy reference to correct sizing when the time comes for the rest of you guys.


Engine air filter:
Subaru OEM Part #: 16546AA12A(all the number zero, not the letter 'O').
Aftermarket: Fram CA9997
-Still looking for other aftermarket filters that will fit.


A/C Cabin/Pollen filter:
Subaru OEM Part #: 72880FG000
-Still looking for any aftermarket filters that will fit.

Please make a post if you are running an aftermarket air filter or cabin filter that fits properly!

Thanks,
Mr. E

Engine Air filter = same as Legacy GT 05+
Use that as a cross-reference and alot more options become available.
FRAM, ACDelco, K&N, Blitz, the list goes on and on

bumpage!

I think I want to stock up on some cabin air filters...at 32500 and have yet to replace one. Would be sweet if I could find one that is reusable after cleaning like our intakes! Any one have any incite or is it just going to be replace over and over again?
