Transform your Grand Cherokee's 3.6L V6 into a more responsive powerhouse with this precision-engineered cold air intake system—delivering up to 10% horsepower gains, improved throttle response, and a satisfying sporty engine tone that makes every drive more commanding.

Unleash the Hidden Power of Your Grand Cherokee's Pentastar V6

The Jeep Grand Cherokee has been the flagship of American SUV capability since 1992, blending luxury, off-road prowess, and dependable performance. The 3.6L Pentastar V6 in your 2016-2020 model produces a respectable 295 horsepower and 260 lb-ft of torque from the factory—but those numbers tell only part of the story. Jeep's engineers prioritized quiet cabin comfort over maximum airflow, meaning your factory airbox creates a bottleneck that limits your engine's true potential.

This Cold Air Intake System eliminates that restriction. By replacing the restrictive factory components with lightweight T304 aluminum piping and a high-flow filtration system, it feeds your Pentastar engine the volume of cool, oxygen-dense air it needs to perform at its peak. The result? An estimated boost of 20-30 horsepower and 15-25 lb-ft of torque (up to 10% gains), translating to noticeably sharper acceleration, improved passing power, and a deeper, more aggressive engine note that announces your presence on the trail or highway.

Key Features at a Glance

  • Proven Power Gains: Delivers up to 10% increase in horsepower and torque—approximately 20-30 hp and 15-25 lb-ft on the 3.6L Pentastar V6.
  • Premium T304 Aluminum Construction: Lightweight, corrosion-resistant piping withstands harsh conditions while improving airflow efficiency.
  • High-Flow Filtration: Advanced filter captures harmful debris while maximizing oxygen delivery—cleanable and reusable for long-term value.
  • Enhanced Throttle Response: Eliminates intake lag for more immediate acceleration and confident merging or passing.
  • Sporty Engine Tone: Produces a deeper, more aggressive induction sound through optimized airflow routing.
  • Low Maintenance: Washable filter requires cleaning only every 50,000 miles under normal driving conditions.

How It's Used: Installation & Fitment

This is a direct bolt-on upgrade that replaces your factory air filter and intake tube with minimal effort. Most DIYers can complete installation in under 60 minutes using basic hand tools—screwdrivers and socket wrenches are all you need. Simply remove the factory airbox, install the new aluminum intake piping, secure the high-flow filter, and tighten all connections. Professional installation is highly recommended for those less familiar with engine bay work. After installation, disconnect your battery terminal for 30-60 seconds to reset the ECU, allowing your engine computer to relearn and optimize for the increased airflow.

Product Durability & Material Details

Built from T304 aluminum—the same material used in exhaust systems and performance applications—this intake piping resists corrosion from road salt, moisture, and temperature extremes. The lightweight construction reduces unnecessary weight in the engine bay while maintaining structural integrity under vibration and heat cycling. The high-flow filter uses multi-layer cotton gauze construction that captures contaminants down to microscopic levels while allowing maximum airflow, ensuring your engine breathes freely without sacrificing protection.

Your Benefits at a Glance
  • Commanding Acceleration: Noticeably improved throttle response makes merging, passing, and trail climbing more confident and capable.
  • Better Fuel Economy: Optimized air-to-fuel ratios can lead to improved fuel efficiency during highway cruising and normal driving conditions.
  • Long-Term Value: Reusable, washable filter eliminates the need for costly replacements—clean every 50,000 miles and reinstall.

Installation & Tools

The Wrench Time

  • Estimated Time: 45-60 Minutes
  • Difficulty: 3/10 - A straightforward bolt-on, but requires a delicate touch when handling the fragile factory Pentastar sensors.

Tools You Will Need

  • 10mm deep socket and ratchet (for the battery and airbox mounting bolts)
  • 8mm socket or nut driver (for OEM worm gear clamps)
  • Flathead screwdriver
  • Panel popper tool (to safely detach the wire harness clips without snapping brittle WK2 plastics)
Mechanic’s Pro Tip (The "Gotcha"):
The WK2 community knows the 3.6L Pentastar Intake Air Temperature (IAT) sensor is notoriously brittle. When removing it from the factory intake tube, do not yank it. It requires a gentle quarter-turn counterclockwise. If you pry on the locking tab with a heavy hand, you will snap the plastic ear right off, leaving you stranded with a massive vacuum leak and a Check Engine Light. Treat the thermistor bulb like glass—do not touch it with your bare fingers.

Phase 1: Removing the Factory Part

  1. Disconnect the Battery: Always start by disconnecting the negative battery terminal using a 10mm wrench to prevent check engine lights and allow the ECU to reset for your 2016-2020 Jeep Grand Cherokee 3.6L.
  2. Unplug the IAT Sensor: Locate the Intake Air Temperature sensor on the factory intake tube. Slide the red locking tab back, press down on the release clip, and gently pull the connector free. Use a panel popper to pry the harness anchor out of the plastic tube so the wire hangs completely free.
  3. Loosen the Clamps: Grab your 8mm socket and loosen the hose clamps securing the factory intake tube to the throttle body and to the airbox. Do not unthread them completely; just loosen them enough to break the seal.
  4. Disconnect the PCV Breather: Unclip the crankcase breather hose from the side of the airbox. Depending on your exact model year, this will either be a friction fit or have a small grey push-release button. Press the button and pull straight back.
  5. Yank the Silencer: Lift the bulky factory Helmholtz resonator (the massive plastic silencer box) and intake tube up and away from the throttle body. Set it on your workbench.
  6. Remove the Lower Airbox: Remove the single factory mounting bolt holding the airbox to the fender using a 10mm socket. Grab the entire airbox assembly and pull straight up. It is held into the frame rail by three rubber friction grommets. A firm upward yank will pop it loose.

Phase 2: Installing the Cold Air Intake for Jeep Grand Cherokee (2016-2020) 3.6L V6 Engine

  1. Transfer the IAT Sensor: Gently rotate the IAT sensor counterclockwise to remove it from your OEM tube. Inspect the O-ring for tears. Push it firmly into the rubber grommet of your new intake tube and twist clockwise to lock it in. Do not touch the sensor bulb with greasy fingers.
  2. Drop in the Heat Shield: Lower the new aftermarket heat shield and filter housing into the engine bay, aligning the bottom posts with the factory rubber grommets. Push down firmly to seat them, and secure the housing to the fender using the factory hardware and your 10mm socket.
  3. Mount the Couplers: Slide the provided silicone coupler over the 3.6L throttle body and secure the clamp using an 8mm socket. Slide the other end onto the new intake tube. Leave the tube-side clamp slightly loose so you have wiggle room for alignment.
  4. Connect the PCV and Harness: Attach the crankcase breather hose to the new aluminum fitting on your aftermarket tube. Plug the wire harness back into the IAT sensor, ensuring you push the red locking tab forward to secure it.
  5. Final Torque and Alignment: Verify the aftermarket air filter is seated tightly in the heat shield, check that the tube is not rubbing against the radiator hose or engine cover, and tighten down all remaining clamps with your 8mm socket.
  6. The ECU Relearn Procedure: Reconnect the negative battery terminal. Turn the ignition to the ON position (do not start the engine yet). Start the engine, and do not touch the gas pedal for 20 seconds. This allows the 2016-2020 Jeep Grand Cherokee 3.6L ECU to calibrate to the new, higher volume of incoming air and prevents rough idling.
