Go to www.rangerpowersports.com they have a 4.0 section for HP & also a California club to help with emmissions.

ya cool site but thay dont have much for my ranger

check out www.therangerstation.com
under the assorted catagories there is stuff for 4.0 engines

summit racing has every aftermarket part avalible for almost anything. all you can do is exhaust,air filter system & computer chip.your manual trans swap will be more work than its worth.they do also sell bigger throdel bodies and mass air flow sensors.
