I have an MAPerformance short ram right now, and let me tell you it heat soaks to shit after a few pulls. I built a headlight with a NACA duct similar to what you bought, it worked alright on the track, but obviously I can't drive around with that on normally. Not super concerned about sound or looks, I'm also a function > form guy and the ITG is the only one that sits outside the engine bay. I was always just concerned with water getting in, and its placement in the bumper.
