Are there any type of upgrades that i can do to my 04 pathfinder Le? I mean ANY thing that can give me more horsepwr money isnt a problem unlesss its gonna cost me more than 2 g's. I've covered the intake, and Im looking at jet performance chip ( anything better?), but not sure yet cus I need my car daily.

Also Im looking to get a hitch for my car But theres one thing Im wondering... Will i still be able to mount my extra tire under my car?
