Help me soup up my boxster

[Topless]

Jake,

I have used K&N filters since the 70's in off road racing. They worked great in that application but we cleaned them every race and rebuilt the motor every 10 races. I don't want to do that with my Porsche. I have studied the dyno runs, compared flow rates and particle intrusion testing and the K&N doesn't make sense to me on a M96 motor. A good clean paper filter still looks like the way to go. If we significantly increase displacement or intake flow rates, we may need a larger tuned intake and larger paper filter but a K&N still isn't clean enough.

I appreciate your knowledge and experience with Porsche motors and I have learned a lot from you about the internals of this very German machine. I have to agree with Mike on this. The K&N filter goes against everything you have been saying about improving the reliability of M96 motors over the past year. It is inconsistent with your design philosophy. Give this some thought while you ramp up production as a major player in the Porsche M96 aftermarket business.
