anything up to 3" just have to take the plastic top off the filter and get rid of the studs holding it down, the hood will hold your filter on just fine, held mine for over a year....3.5" you may have to trim some hood supports....anything more then, and dont want a hole in your hood you have to get creative....my trucks bd'd 6" with a completely stock hood, didnt even cut hood supports. well not for the motor anyhow, cut them for the wheels.
