if your engine is otherwise stock don't expect huge increases, just a better pull from 3000 up. I think cold air would be better than the drilled box deal because the hole in the fron suck up warm air from the engine bay.(note what I say is just my experience) so i'm gonna run an intake pipe down to just behind the lower radiator grill. Yeah i wouldn't spend to 200 for a pre-made intake it won't do that much. but it is worth the 40 bucks of a k&n filter
