I liked my AUT and Cusco plates to an extent, but actually just reinstalled my OEM plate (which was a pain). My initial reaction after reinstalling it? "Ah, it fits right, and my hood closes easily... nice." My AUT plate scratched my intake box and even the paint a tiny bit along the sides. My Cusco one prevented the hood from easily shutting and came in contact with the hood latch. Did I lose 1-2 horsepower? Maybe, but I doubt it. For the record, I only have a K&N drop in filter, not the kit.
