I've got a APS K&N filter sitting here plus a recharge kit for it that you could grab.

But as others have said, DON'T put a K&N oiled filter on your 99/00 WRX/STI period. It will fuck the AFM.

APEXI dry pod filter only.
Or keep you standard airbox/filter, resonatorectomy, CAI pipe from front bumper into the airbox and do a silicon intake pipe to turbo. Good for 220ish KW ATW.
