any of these filters are going to be better than stock..i happen to be very pleased with my kkm..i can feel a better throttle response...and i'm comparing that to a k+n,which is what was on my car when i bought it...kkm totally outperforms it..and the price isn't too bad considering that mirko wants the same price for just the adapter..personally i think that you will probably be happy with any of the aftermarket filters..anything is better than the stock paper element..just my opinion though..
