Very little if any improvement for both performance and mpg, had the set-up on my 99 RC 4x4 with 3.9 and it was not worth the $$ IMO. Came with a great set of lifetime 8.5mm plug wires though... Go with a cold air intake and flowmaster single pipe catback exhaust instead for the almost the same $$ and you WILL notice the difference with those mods, I had K & N FIPK and Flowmaster and they made a very good combo for added performance, did nothing for mileage because I was always standin on the gas pedal:)
Flowmaster stainless cat back, Air Raid CAD and homemade TB connect, Poweraid TB Spacer, Splitfire Plugs
3 inch body and 1.5" block lift, 33x11.50-16's, Superlift Truspeed Recalibrator
Powerslot Rotors, Ceramic Brake Pads
