I think i will choose apexi filter after saw ur link hehehe. Can tapis those dirt better then other brand. K&N is also good use before on my other car last time but only it looks dirty after u use it long.That I dunno, I always stick to K&N, brand loyalty
I havent seen an Apexi 'maintainence' or 'recharger' kit ever, have you?... :hmmmm: I know the blitz one is lifetime use though, haha.
