I plan to do some engine mods to my little 3.0 but not sure where to look for parts despite my searches with google. I did find a CAI kit. My first question, will I have to have it tuned after the CAI install? I know some OBD II systems are finicky not sure on the rangers tho. next, I'm having a hard time finding shorty headers, seems everyone has them for the 4.0 but not the vulcan. Does anyone make an aftermarket intake or TB for the vulcan? or can I adapt a aluminum intake from an earlier yr 3.0? and finally, I want to do a rear disc swap on in but have been told a couple dif stories. I've heard I can use my axles and just mount the disc hardware to my backing plates and be done, another says I have to use the axles from a explorer with rear disc. This would be more doable since I want to get rid of the peg leg anyway and install a trac-lok unit. Thanks for the advice.
