"I installed the K&N 63 series along w/Gibson Exhaust. Definitely not the same Jeep Renegade, it's like a Jeep on Steroids. The pickup is phoenominal, but the exhaust in cab noise is loader than I thought. I have kids and a wife so, I'm a bit more reserve when it comes to load noise, but I do love the performance and the noticeable difference on gas (chaachiing!!!)." —Jamie A from Pueblo, CO bought a Jet Performance Module for a 2004 Jeep Liberty.
"The jet module is a product good for the money. However i did not notice much performance from the module. The most noticable improvement was the new transmission shift points and shift firmness. Overall good product." —Marcus S from Riverdale, MD bought a Jet Performance Module for a 2004 Jeep Liberty.
"It took all of 5 seconds to insall. Not only did it improve acceleration it also seemed to make the transmission shift better. All in all I think it was worth what I payed for it. Randy" —Randy L from Starkville, MS bought a Jet Performance Module for a 2004 Jeep Liberty.
"The Jet Module did give a little extra power thru th eRPM curve, but most of all it did change the shifting points in the tranny so that now it doesnt shift in and out of overdrive when traveling thru the mountains. I had some questions prior to the instalation and called customer service and they were verry helpfull with all my questions." —Robert A from Bloomington, IL bought a Jet Performance Module for a 2004 Jeep Liberty, 3.7L V6.
