i think your next mod should be a custom exhaust system. check out mine, i also have a 3.0

also you can get the aFe CAI .. easy mod.
other mods:
-new headlights or get AEs in yours/remove waffles
-4.6 kit (i would love this)
-you can go with some BSW options for your sound system.. i got their speaker upgrade..its pretty good..workin on getting their stealth sub.
-HID fogs 6000k
and thats all that comes to mind at 2:13 am lol
also, i'm not a fan of the chrome door pillars. just my opinion. and if you could get a few more pictures of your tailights that would be awesome.. especially at night. would be interested to see them.
nice X. keep modding!
