4.0L 6-CYL: 1998-06 WRANGLER
PowerPack combines all of Banks' 4.0L Jeep airflow upgrades to maximize power no matter what the terrain. It starts with the free-breathing Banks Ram-AirÂ® Intake and high-flow MonsterÂ® Exhaust, then adds torque-optimizing exhaust manifold (Banks RevolverÂ® for 1998-99 models or TorqueTubesÂ® for 2003-06). PowerPack unleashes the power your engine wastes trying to overcome factory intake and exhaust airflow restrictions. By improving engine efficiency, more power gets to the rear wheels, your engine lives longer and fuel economy improves.
