Conversation Between CobraXP and superdutyduck

hi my name is charlie, i've seen a post of yours in the utah chapter forum, i think your exploder is damn good lookin. Im buying an 02 explorer and will be picking it up in a couple weeks. it is solid black and tinted out full leather, yep will be adding it to my profile. any way are there any good upgrades for the 4.0 that will boost the power with out sacrificing to many expensive parts? thanks charlie
