K&N Series 50 NextGen Cold Air Intake with High-Flow Oiled Air Filter (20-26 6.6L Gas Silverado 3500 HD)

High-Flow Air Intake System. The K&N Series 50 NextGen Cold Air Intake with High-Flow Oiled Air Filter is designed to increase engine airflow efficiently, delivering improved horsepower and torque gains on a stock tune without requiring any engine modifications or tuning. It replaces the factory air intake to provide enhanced airflow while maintaining contaminant protection.

Construction and Appearance. The intake tube is made from durable, heat-resistant high-density polyethylene manufactured through rotational molding, featuring a sleek black finish. The hybrid semi-enclosed airbox design helps to reduce intake air temperature. The oversized conical filter uses oiled cotton gauze media for reliable filtration and is washable and reusable, allowing up to 100,000 miles between services under normal driving conditions.

Installation. Installation typically takes under 60 minutes and uses Quick-Lock technology to simplify filter attachment while reducing mounting hardware complexity, resulting in a secure fitment. No drilling is specified or required during installation.

Warranty. This intake system includes a lifetime limited warranty that does not affect the vehicle’s factory warranty, providing long-term coverage.

Application. Engineered specifically for Chevrolet Silverado 2500 HD and 3500 HD models equipped with the 6.6L Gas V8 engine from years 2020 through 2026 to ensure precise compatibility and fitment.
