Unlock additional horsepower, torque, and improved airflow with the K&N NextGen Cold Air Intake System engineered specifically for the Jeep Wrangler JL and Jeep Gladiator equipped with the 3.6L V6 engine. Designed to maximize engine breathing while maintaining factory drivability, this premium intake system delivers dyno-proven gains of up to 14.0 horsepower and 16.1 lb-ft of torque without requiring an ECU tune.

The system features a large-diameter, CAD-designed high-density cross-linked polyethylene (HDPE) intake tube that increases airflow volume by up to 65.4% over the factory intake system. Strategically positioned air channels improve airflow velocity and deliver a larger volume of cool air to the engine, resulting in improved throttle response, stronger acceleration, and increased overall performance.

The oversized washable and reusable High-Flow LIFETIME Air Filter™ utilizes premium oiled cotton gauze media to provide exceptional airflow while maintaining excellent filtration. Its oversized conical design and radius-entry inlet maximize airflow efficiency and allow service intervals of up to 100,000 miles under normal highway driving conditions before cleaning is required.

A custom-engineered NextGen hybrid airbox features a semi-enclosed design that shields the intake from engine bay heat while incorporating an enlarged fresh-air inlet for greater airflow and improved protection from dirt, dust, and other contaminants.

Unlike traditional intake tubes, the rotationally molded HDPE intake tube is designed for smooth airflow with optimized internal geometry that minimizes restriction while enhancing engine efficiency. The black finish also provides a clean, factory-inspired appearance under the hood.

During acceleration, the intake delivers a deep, aggressive induction sound while remaining quiet during normal highway cruising, making it an excellent upgrade for both daily driving and off-road adventures.

Installation is simplified with reduced mounting hardware, Quick-Lock™ filter technology, and a sealing bead that secures the intake using a single hose clamp. Most installations can be completed in less than 60 minutes using basic hand tools.

Since 1969, K&N has been trusted by racers, off-road enthusiasts, and performance builders worldwide. Backed by a No-Hassle Lifetime Limited Warranty, the NextGen Cold Air Intake offers long-lasting performance, superior filtration, and dependable durability while helping preserve your factory vehicle warranty.
