I used an 11"x5" K&N assembly with the velocity stack style base. Fit inside my Harwood snorkel with an isolator plate. My scoop is mounted on the engine and stays on the car when the hood is removed. Made a difference in the looks of the cylinder walls at the end of the year. And I don't worry about rocks and junk getting thrown into the scoop. Wouldn't be with out it now.


If the results don't match the theory, change the theory.
