Performance Enhancement. The Rough Country Cold Air Intake improves horsepower and throttle response by drawing cooler, denser air from outside the engine compartment. This increases oxygen availability for better combustion and engine efficiency, resulting in a noticeable boost in power while protecting the engine from harmful debris.

Built with high-quality materials, this intake system features a cylindrical, large-diameter intake tube and a premium reusable air filter designed for durability and sustained performance. The included heat shield helps keep intake air cooler, and durable clamps and hardware secure the system for reliable, long-term use.
Installation. Installation is straightforward and typically takes 1–2 hours without requiring any major modifications or drilling. The system is designed for a clean, bolt-on fitment, ensuring an easy upgrade process.
Warranty. This product carries a limited lifetime warranty for peace of mind.
Application. Specifically designed to fit 2017 to 2019 6.6L Duramax Silverado 3500 HD models, with compliance notes excluding sales in California and similar regulatory states.
