Just wondering what air filters you guys use / recommend for this situation:

MY99 WRX with std turbo and full 3" exhaust with w/gate splitter - no other engine mods to speak of... Just bought an APS CAI and wondering what air filter I should use. I don't want AFM problems so i'm thinking a non-oiled filter is going to be best.

Basically wondering what kind of filters are best and where's the best place to pick one up?

Thanks lads!

Jacob.
