Cold Air Intake | 6.6L | Chevy/GMC 2500HD/3500HD (17-19)

Unlock More Power: Give your engine the airflow it deserves with Rough Country's Cold Air Intake System. Designed to increase horsepower, improve throttle response, and enhance overall engine performance, this premium intake delivers cooler, denser air that helps your engine produce more efficient combustion and stronger acceleration. Whether you're towing, commuting, or exploring off the beaten path, you'll enjoy a noticeable improvement in performance every time you press the throttle. Maximize Airflow Efficiency: Factory intake systems can restrict airflow and limit your engine's potential. Rough Country's free-flowing intake design relocates the air filter away from the hot engine compartment, allowing it to draw in cooler outside air. Combined with a large-diameter intake tube and high-flow cylindrical filter, this system dramatically improves airflow over the factory airbox, helping your engine breathe easier for increased power, efficiency, and responsiveness. Premium Reusable Air Filter: Each intake includes a high-flow, washable, and reusable performance air filter engineered to provide exceptional filtration without sacrificing airflow. Simply clean, re-oil, and reinstall the filter to maintain peak performance while eliminating the recurring cost of disposable replacement filters. Simple Bolt-On Installation: Upgrade your vehicle with confidence. This intake system is engineered for a straightforward installation using factory mounting locations, requiring no cutting or permanent modifications. Spend less time in the garage and more time enjoying the added performance. Built to Last: Constructed from premium-quality materials, Rough Country's Cold Air Intake is built to withstand the heat, vibration, and demands of both daily driving and off-road adventures. Durable construction ensures dependable performance mile after mile. Optional Pre-Filter Protection: For drivers who frequently encounter dust, sand, mud, or other harsh environments, an optional pre-filter bag is available to provide an additional layer of protection. This accessory helps shield the reusable air filter from excessive debris, extending cleaning intervals while maintaining excellent airflow. Limited Lifetime Replacement Warranty: Backed by Rough Country's Limited Lifetime Replacement Warranty, this Cold Air Intake delivers the performance, durability, and confidence you expect from a trusted name in off-road performance.
