Next-Level Airflow. The K&N Series 50 NextGen Cold Air Intake is engineered to significantly increase engine airflow and overall performance while maintaining factory-style drivability on 2020-2026 6.6L gas Chevrolet Silverado 3500 HD models. Designed as a performance-focused upgrade, it plays a critical role in improving throttle response, power delivery, and engine efficiency under daily driving and demanding workloads.

Construction and Appearance. This intake system features a matte black finish housing paired with a matte black high-flow oiled air filter for a clean, performance-oriented engine bay appearance. The CAD designed large-diameter intake tube is optimized to support the oversized filter, allowing smoother and less restrictive airflow. With dyno-tested gains of up to 20.56 horsepower and 28.1 foot-per-pound of torque, along with an airflow increase of up to 83.2%, the system is engineered to deliver measurable performance improvements. Quick-Lock technology allows for easy filter switching, while precision-molded components ensure consistent airflow and long-term durability.

Installation. Designed as a direct replacement, installation is straightforward and does not require cutting or permanent modification. The system includes all necessary hardware, fittings, gaskets, and adapters to support a clean, secure installation using basic hand tools. Once installed, the intake integrates seamlessly with existing engine components, allowing the upgraded airflow system to perform reliably without additional tuning.

Warranty. This cold air intake is backed by a no-hassle limited lifetime warranty, providing long-term assurance against defects in materials and workmanship. The warranty reflects confidence in the engineering, materials, and performance consistency of the system throughout extended use.

Application. This K&N Series 50 NextGen Cold Air Intake fits 2020-2026 6.6L gas Chevrolet Silverado 3500 HD models. By improving airflow efficiency, increasing horsepower and torque, and enhancing throttle response, it elevates engine performance while retaining reliable operation for work, towing, and everyday driving.
