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

Engineered for the 6.6L Duramax-powered Chevy/GMC 2500HD and 3500HD (2017–2019), this Cold Air Intake relocates the air filter out of the hot engine bay to pull cooler, denser air for sharper throttle response and more precise power delivery.

• Compatibility: Specifically designed for Chevrolet/GMC 2500HD and 3500HD with the 6.6L Duramax, model years 2017–2019.
• Cold Air Routing: Optimized intake path draws cooler outside-air, increasing air density for better combustion and more confident acceleration.
• Large-Diameter Intake Tube: Cylindrical, high-flow tube delivers greater airflow than stock, supporting stronger throttle response.
• Premium Reusable Filter with Pre-Filter: High-quality filter reduces ongoing costs and includes a pre-filter for enhanced debris protection and easy cleaning.
• Easy Bolt-On Installation: Simple, tool-light setup with no permanent modifications required, designed for a straightforward upgrade.
• Durability & Warranty: Built for long-lasting performance with a Limited Lifetime Warranty.

This Cold Air Intake addresses a common turbo-diesel challenge: hot air in the engine compartment can reduce oxygen density and performance. By pulling cooler air into the engine, your Duramax can deliver more efficient combustion, translating to more responsive acceleration, smoother power delivery when climbing grades, and a more confident overall driving experience. The reusable filter minimizes ongoing maintenance costs, while the pre-filter adds extra protection in dusty environments.
