killershee88 Posted November 3, 2003 Report Share Posted November 3, 2003 just thought id let u guys that r still runnin the stock air box setup to get away from it! if it doesnt go exactly into the slot on the lid your beat. spend the 100 and go with the pro flow. you do ot have to run a lid at all. your see about a 2-3 hp gain.

Banchetta Posted November 3, 2003 Report Share Posted November 3, 2003 I got a 4hp gain by cutting the end of my cover (1.5") so you still have all four clips. Then I gained another 1hp taking the cover completely off. Thats w/ midrange pipes, so I'd think high revs would benefit more. Quote Link to comment Share on other sites More sharing options...
