My next step is to dyno it again and see how the air/fuel is. There is a meager difference from running from just the stock air box. Before I added this, I took the stock air box off and put a 3.5" cone(what you see in pic) right to the mass air meter and that made a meager diff as well. I was happy with that just by it's self but I was hip deep in the fab of the carbon fiber tube and went all the way*Bling*.
