There are lots of less expensive / or destructive ways to add the intake. Why not pull in air from the grill? If it's boxed in, you could tack in a NACA duct (or two) and not affect performance in any way negatively. Nice cold air, free of turbulence, and very high performance. While you are at it, you could drop in two for brake cooling. They are available in a number of sizes and materials, easy to install and the highest of tech and stealth. When the latest iteration of the Corvett came out a few years ago they were pulling hot intake air from the engine bay. My boss bought a kit that opened a slot in the front grill that was doing nothing but pushing air away from the front end. It was a crappy kit and I suggested using the NACA duct instead of the junk kit. Well he poo paad that idea as if he knew better than anyone about engineering. Guess how stock Corvetts are getting their intake air now?
