The Football

RE: The Football
here is something I found out last week about the KN filter and the football cover. I had my2006 Superglide in for dyno tuning after doing a 95" build. The builder/tuner was shaking his head, couldn't figure out why he wasn't getting the numbers he expected. I thought maybe the velocity stack had come lose or something and was blocking the intake, he took the air filter off and all was in place. So Isaid, do a run with no air cleaner, just the velocity stack, and picked up the 7 horsepower he was missing. He said a filter should only drop it 2 horsepower or so, couldn't figure out why a KN didnt flow better. So I said, lets run it with the filter but without the football cover...it dropped about 2 horsepower but we were up 5 over what it was with the football on. I am planning to drill some 1/2" holes in the bottom of the cover when I get a chance. The filter has clearance on the cover at the front and rear, but on the top and bottom it is aclose fit,restricting air flow thru there.
