Cold Air Intake for Jeep Grand Cherokee (2016-2021) 3.6L Engine

High-Velocity Induction for the 3.6L Pentastar V6

Who It’s For: Engineered for Jeep Grand Cherokee owners running the 3.6L Pentastar V6 powerplant who are tired of the stock sluggishness and delayed throttle response inherent in the heavy WK2 chassis.

The Symptom: The factory intake on the Pentastar V6 is designed for silence above all else. It utilizes restrictive resonator boxes and corrugated plastic tubing that creates massive air turbulence, effectively choking the engine’s ability to breathe during high-load situations. When you’re trying to pass on the highway or accelerate from a stop in a 4,500-pound SUV, this lack of immediate airflow creates a noticeable "dead spot" in your power band.

The Engineering Fix: This system replaces that restrictive plastic plumbing with a high-grade mandrel-bent aluminum tube, ensuring a constant diameter and smooth internal surface. By utilizing a dedicated heat shield, we isolate the air filter from the radiant heat of the engine bay, ensuring the oxygen density remains high. Cooler, faster-moving air allows the engine’s computer to optimize combustion, resulting in a sharper throttle snap and a much more aggressive induction growl under heavy acceleration.

Why Mechanics Choose This Kit

• Optimized Power Delivery: Boosts horsepower and torque by up to 10% by reducing the vacuum restriction found in the stock Pentastar airbox.
• Aggressive Acoustics: Replaces the factory baffles with a straight-through design that provides a deep, throaty roar when the variable valve timing kicks in.
• Premium Construction: Built with T304 lightweight aluminum piping and a washable, high-flow cotton media filter designed for long-term durability.
