The Avenger Supercharger for the 4.0L Jeep engine adds 100hp and 55% more torque. Due to the efficiency of the intercooler, we are able to achieve this level of performance at only 4.5-5 psi of boost.

What's Included

The standard kit includes a 2 bar map sensor, a DiabloSport Tuning System, larger 400cc fuel injectors, an intercooler, cold air intake system, and a hood scoop. You can upgrade to a DiabloTrinity Tuner for an additional cost.


Each kit includes detailed installation instructions and can be handled by most skilled home mechanics. Of course, we suggest installation by one of our trained and skilled dealers in your area. You can download installation instructions here.
