Adam, don't bother with the K&N. Been there, done that. Didn't notice any improvement in performance. Did notice that the intake noise level went up though. Maybe making a benz sound like a NASCAR rig gets people to thinking it's more powerful. At any rate flow dynamics won't really show improvement until the upper end of the RPM stretch. By then you should have left all the Detroit iron in the rearview. Try it if you must, let me know your impressions. A clean MBZ element should be just as good.
