One good thing about the under tray vs other mods, even if it's not that great of an aero-improvement, it helps to keep your engine bay clean, which is nice for when you're working in there.

Also, a clean engine could be running more efficiently than a dirty one. The grease and grime kind of holds the heat into the engine, in the wrong places, IMO. I prefer to keep it clean. A bottle of simple green and some water will get you a long way in making the underhood area a little more tolerable to mess with.
