Fit under my 4″ aircleaner not sure on actual gains but I have seen dyo graphs. Main thing is check your jetting after some people have to go up a step

These used to fit just fine. The newer ones absolutely don’t fit. Tried to Dremel it still wount fit. Save your $70. Mine went into the trash same day I got it. Never had a k&n issue before now.
