As requested, I uploaded two pictures of the Kenne Bell supercharger on our 4.0 liter motor. Yes its CARB ("California Air Resources Board") approved! I added an AEV Heat Reduction Hood, Flow Kooker high flow water pump, Turbo City high flow thermostat housing, and 7-blade Mopar fan to make sure it runs cool, even in the desert.
Also a pictures of our Jeep on a local trail near Big Bear so you know its not a poser.
Hope to see you on the trail sometime!
