Unlock Serious Power And Breathe New Life Into Your Truck

If you are ready to wake up your Silverado 2500HD or 3500HD, the K&N 50-3103 NextGen Cold Air Intake delivers a noticeable punch in performance. Designed to feed your 6.6L V8 with 83.2% more airflow, this intake helps you unlock an extra 20.56 horsepower and 28.1 lb-ft of torque without ever needing a tune. The difference is felt the first time you hit the throttle, whether you are towing up a steep grade or merging onto the highway. K&N pairs this intake with a washable, reusable High-Flow LIFETIME Air Filter so you can forget about buying replacements and focus on driving. The oversized conical filter can go up to 100,000 miles between cleanings under normal conditions, making it as practical as it is powerful. A custom-designed NextGen air box shields the intake air from under hood heat, keeping it cool and dense for better combustion. With an installation that can be wrapped up in under an hour using basic tools, this intake is the kind of upgrade that pays off every time you turn the key.

Precision Engineering Built For Real Performance Gains

Every part of the K&N 50-3103 NextGen Cold Air Intake is engineered with performance and durability in mind for your 2020-2025 Silverado 2500HD or 3500HD 6.6L V8. The high-density polyethylene intake tube is rotationally molded and CAD-designed to create a smooth, large-diameter path for air, reducing restrictions and boosting airspeed. A semi-enclosed NextGen air box with an enlarged fresh air inlet protects the intake charge from engine bay heat while drawing in cooler outside air for improved combustion. The oversized oiled cotton air filter offers a massive surface area and radius-entry design that allows your engine to breathe easier while maintaining excellent filtration. This intake has been dyno-tested to provide a guaranteed increase in horsepower and torque while preserving your factory tune, so you get reliable gains without added complexity. K&N's Quick-Lock technology makes filter changes simple, snapping into place securely with minimal hardware. Backed by a Lifetime Limited Warranty and proudly engineered in the USA, this intake offers proven performance and long-term reliability trusted by truck enthusiasts everywhere.
