Since the stock air box has the snorkel tube supplying air to the stock filter I thought why not leave the bottom there and keep the top open! I cut the air box lid to fit and then used the gasket from the stock air filter to keep it secure once its snapped in. I think it looks cool and is different.I am going to make a better looking bracket to keep the filter in place,the one there was a quick fix. The one thing I will say that I noticed is the sound it makes at WOT is very throaty with the way I have it now. Its as if the box is amplifying the sound. Anyway opinions on the the looks and function?
