The air filter itself is a very large unit and in a cannister that is about 12" in diameter.

The engineers say it is the short, hard 90° turn that hurts the pancake style filters.

I have a canister that you can borrow to have a copy fabricated at some point if you can't find the real deal, Chuck. Lord knows it's not going to be on my car anytime soon. Can't wait to see the dyno. Incidentally, I have a device somewhere that has an accelerometer in it and can theorhetically tell you how many ponies you have by inputing the car's weight. Might be fun to try it sometime. I’m firmly in the stock camp, myself. I have a canister that you can borrow to have a copy fabricated at some point if you can’t find the real deal, Chuck.

If you look closely, though, they can theoretically reduce the life of your engine as they let more through the filter. A coffee filter made of a fence, so to speak. While most people say that K&N filter systems are a great add on to a car, and I have seen them increase performance on everything from a little Toyota Corolla to a Dodge Stealth TT, I simply can't trust them on any of my vehicles. The last thing I want is even more crud entering my engine. I say good call on replacing it, but once again, it's more pointless internet debate. :) Also, emacs sucks. :) One thing I’ve found regarding K&N filters is they do let a /lot/ of air into the system.
