Description:
K&N High Performance AirCharger Air Intake System for 3.7L engines are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your Jeep's engine to inhale a larger amount of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range.
