H3 Engine Repsonse - K&N Filter

[ChevyHighPerformance]

f5fstop,

I noticed that you mentioned this before about the K&N filters not filtering as well as the stock paper filter. I thought the K&N's did pretty well. The problem with the stock H3 paper filter is the pleat depth/density ratio is too high and actually reduces the active filter surface area. This is why the K&N's work better in the H3's than the C5's as far as flow/power goes.

Did you do your test on a C5? The Fram filter did as well as the K&N. An advantage of the K&N is that it is not damaged by water and helps stop water from entering the intake. Some vettes and f-bodies had low air scoops that directed water (and air) into the air box where the water dissovled/weakened the paper filter and water entered the intake and hydro-locked the engine.

You should see the air filter on the new C6 Z06. I rode in a preproduction model about 2 months ago. The new Z06 spanks the GT-40 at half the price and easily de-fangs the Viper. And, if you think new Z06 is fast wait until you see what's next.....
