The '02 Jeep Liberty 3.7L V-6 engine was in stock form. The vehicle had already received a Frankenlift from All J Products and was equipped with 31-inch Goodyear Wrangler MT/Rs on Moab wheels from a Wrangler Rubicon. Though the engine still offered a good degree of power, we wanted to see how much more power could be created through use of the aFe intake and MagnaFlow exhaust.
