"My Jet module was pretty easy to put in although the radiator overflow tank was in the way. If that tank wasn't there, it would have taken 5 minutes to install. I went for a ride and noticed a nice increase in power. I would recommend this for a great all-around increase in performance that does not seem to make the gas mileage any worse." —Stephen H from Parker, CO bought a Jet Performance Module for a 2011 Jeep Grand Cherokee, 3.6L V6.
