Either are fine mate.
If you're overly bothered about tiny particles getting in the engine I'd run OEM.
If you prefer to have a reusable filter stick with K&N, though you need to buy a refresh kit.
Main thing with K&N is to not over oil it as it can muck up the MAF.
Performance-wise you won't feel the difference so go with your personal preference.
