[QUOTE="900gc, post: 955211, member: 28365"] I just did my airbox the same way as FJRed and firstly noticed the increased intake noise. It howls more when cranking on it and drones more at steady throttle. I don't mind the extra noise but it is noticeable. My "butt dyno", (which, as a veteran expert racer, has become pretty sensitive and accurate) senses a little more pep in throttle pick up. Now how this translates into measured dyno #'s and 1/4 mile times, I do not know. If I grow tired of the extra intake noise, I'll just fashion a plate to cover the cutout and put the covers back on the access side. The snorkel will remain gone but IMO, is only there for EPA, etc. noise reduction reasons. Go for it. It's easy enough to undo. BTW: PC maps can modded cell by cell. As long as you don't go crazy changing the #'s by a ridicules amount either way from a good map, you can pick up a couple MPG while still having improved fueling. [/QUOTE]
