But that's just guessing. Hp really cones down to tuning, cam, cubes, etc. A customer might move the air filter and get more power out of the kit then his buddy did. My filter is mounted off to the side and probably will reinstall the stock box and see if it helps air temps. If it does that item might get pulled and the price would go down ;)
