Great graph! But I wanted to see how it would effect a two-valve car...these are especially exhaust sensitive. I've heard adding headers to one of these makes a huge difference.

I've personally seen the K&N make less power on the dyno on several different 928s, I know of others that have seen the same thing, and I've also seen where the same thing occurred on some BMW dyno tests. The K&N filter *MAY* flow more more air per square inch of filter media, but it has a lot less filter area than the stock Porsche filter. The K&N filter has a little over 350 square inches of filter area, and the stock filter has almost 1,350 square inches.
