Actually, I know a few people who have replaced the entire air cleaner box with a simple K&N cone filter sitting directly on the throttle body. There did seem to be a bit more power. And locally, the Neidel family runs their race-only car (D-jet 2.0, Euro pistons, full headers) with nothing on top of the throttle body at all. They say it makes a bit more power that way, and they have enough experience for me to believe.
