K&N 2011-2021 Jeep Grand Cherokee NextGen Aluminum Cold Air Intake

Upgrade your 2011-2021 Jeep Grand Cherokee 5.7L V8 with the K&N NextGen Aluminum Cold Air Intake. Boost airflow up to 33%, gain horsepower, and enjoy easy DIY installation in under 60 minutes.

Unleash the full performance potential of your 2011–2021 Jeep Grand Cherokee 5.7L V8 with the K&N NextGen Aluminum Cold Air Intake System. Engineered to replace restrictive factory air intake assemblies, this system utilizes a mandrel-bent 6063 aluminum intake tube to optimize airflow velocity into the engine.

By delivering cooler, oxygen-rich air directly to the throttle body, the NextGen intake produces dyno-proven gains of up to 18.5 horsepower and 31.8 lb-ft of torque—all on a stock tune with no ECU tuning required. The custom-designed NextGen semi-enclosed airbox shields intake air from high engine bay heat, while the oversized washable and reusable High-Flow Air Filter provides continuous, long-lasting filtration. Designed for hassle-free installation, the entire kit mounts into existing factory locations in under 60 minutes.
