Is this tall enough ?

I dont think there would be much gain from sealing the air cleaner to the hood. The hole in the hood is just barley bigger then the aircleaner. Plus on the higway the scoop sucks in so much air that it has no place to go and shakes the entire car :shock:

I think I actually need a bigger hole in the hood. I have to make up supports for the scoop first and see if that helps.
