Nice How-To there!
Have you any idea how much hood clearance there is? I'm assuming if there is any, it's minor and the hood closes for ya. Asking b/c I isntalled a Dynamat hoodliner with stock battery location and air box and the hoodliner gets compressed a bit by the air box when the hood is down all the way. The hoodliner is about 3/4 inch thick and I'd estimate it is getting compressed by 1/8 - 1/4 inch by the stock air box. Just curious, Nice work
