K&N 2012-2018 Jeep Wrangler NextGen Aluminum Cold Air Intake

Boost performance in your 2012–2018 Jeep Wrangler JK 3.6L with the K&N NextGen Aluminum Cold Air Intake. Gains up to +17 HP & +28 lb-ft torque. No tune required!

Unleash the hidden power of your 2012–2018 Jeep Wrangler JK 3.6L V6 with the K&N NextGen Aluminum Cold Air Intake System. Engineered to replace your factory air box and restrictive stock piping, this system utilizes a mandrel-bent American 6063 aluminum intake tube that increases airflow volume by up to 37%. By delivering cooler, oxygen-rich air directly into your engine, the NextGen system provides dyno-proven gains of up to 17 horsepower and 28 lb-ft of torque—giving your Wrangler the low-end grunt and throttle response it needs on highways and rugged trails alike.

Paired with K&N’s oversized, washable High-Flow LIFETIME Air Filter™, this setup features an oiled cotton-gauze media designed to go up to 100,000 miles between services under normal highway driving. The hybrid semi-enclosed NextGen airbox shields cold air from under-hood engine heat while securing the filter with Quick-Lock™ technology. Designed as a direct bolt-on upgrade, it installs in under 60 minutes with basic hand tools and requires no custom tuning or PCM recalibration.
