For a '96 Ram 5.9 a/t. Brand new in box. Never plugged up. I bought this for my tow vehicle, but had no idea 'till I went to take mine out...it already had one. It is claimed to be worth 20hp/27lb.ft. Know of a guy that said it was worth 3/10's gain in the quarter over a Jet module he replaced his with. Mopar Perf. retail is $380. I got this at dealer cost through my dad at $335.45 plus $11.60 ship. Dealer won't take it back!! Would like $315 shipping incl. to lower 48 states. Pics. available if needed and take paypal. Thanks for looking!!
