Description
Cold Air Intake Performance. The Rough Country Cold Air Intake improves engine horsepower and throttle response by delivering cooler, denser air for combustion. It achieves this by relocating the air filter outside the congested engine bay, which enhances airflow and protects the engine from debris.
Construction and Appearance. This intake system features a cylindrical intake tube paired with a premium reusable air filter housed in a heat shield to isolate air from engine heat. The materials are designed for durability and high-quality airflow, ensuring long-lasting operation without performance degradation.
Installation. Installation is straightforward, typically requiring 1-2 hours with no drilling necessary. The kit includes all clamps and hardware needed for a secure fitment, allowing an efficient and hassle-free upgrade.
Warranty. The product comes with a limited lifetime warranty, underscoring its reliability and superior build quality.
Application. Designed specifically for the 2017-2019 6.6L Duramax Silverado 2500 HD, it is not legal for sale in California or other states that follow CARB regulations.
