Upgrade your Chevrolet Silverado 2500/3500 HD with the K&N Engineering NextGen Cold Air Intake system, designed specifically for V8 6.6L engines. This high-performance intake features a rotationally molded high-density polyethylene (HDPE) tube that increases airflow volume by 83.2%, promoting better engine breathing and power output. Installation is straightforward and typically completed in less than 60 minutes, making it a convenient upgrade for serious truck enthusiasts. The system is paired with a washable, reusable High-Flow Lifetime Air Filter, constructed with oiled cotton media, allowing for up to 100,000 miles of use under normal highway conditions without the need for filter replacement.
The oversized, conical filter design maximizes airflow and filtration efficiency while maintaining a compact profile. A custom-designed NextGen air box shields the intake air from the high temperatures of the engine bay, ensuring cooler, denser air reaches the engine. This results in an increase of approximately 20.56 horsepower and 28.1 lb-ft of torque, enhancing overall vehicle performance without requiring an engine tune. Built with durability in mind, this intake system adheres to Prop 65 standards and is compatible with most standard driving conditions. Whether you're looking for improved throttle response, increased horsepower, or enhanced torque, the K&N NextGen Cold Air Intake provides a reliable, high-quality upgrade for your Silverado HD.
Please note that this product is not CARB approved and requires acknowledgment of this status prior to installation. Designed for enthusiasts seeking a simple, effective way to boost their truck*s performance, this intake system is a proven solution with a lifetime air filter that reduces maintenance and maximizes airflow efficiency.
