K&N NextGen Aluminum Intake | 2018-2026 Jeep Wrangler & Gladiator
Upgrade your 3.6L V6 Jeep Wrangler JL or Gladiator JT with the K&N NextGen Aluminum Cold Air Intake. Gain up to 12.5 HP & 47% airflow—no tune needed!
Transform the performance and sound of your Jeep with the K&N NextGen Aluminum Cold Air Intake System (SKU: KNN70-1576). Custom-engineered specifically for the 2018–2026 Jeep Wrangler JL and 2020–2026 Jeep Gladiator JT equipped with the 3.6L Pentastar V6 engine, this system replaces the restrictive factory airbox to help your engine breathe freely.
Built around a mandrel-bent, American-made 6063 rigid aluminum intake tube, the system smooths and increases airflow volume by up to 47% over stock. This translated gain yields up to 12.5 horsepower and 13.3 lb-ft of torque—all on the stock ECU map without requiring a custom computer tune!
The intake features a custom-designed NextGen air box that insulates incoming air from extreme engine bay temperatures, ensuring cooler, denser air reaches the throttle body. At the front of the intake sits K&N's signature washable, reusable High-Flow Lifetime Air Filter made with oiled cotton gauze media. Designed for extreme longevity, this oversized conical filter can go up to 100,000 miles between service intervals under normal highway driving conditions.
Expect a deeper, more aggressive growl under acceleration while maintaining quiet, drone-free operation during highway cruising. Installation is straightforward and typically takes less than 60 minutes using standard hand tools.
