Upgrade airflow and cut under-hood heat soak with this Rtunes Racing heat shield cold air intake kit, built for the 2001-2003 Chevy Silverado 2500HD/3500 6.6L V8 Diesel Engine, 2004 Chevy Silverado 2500HD/3500 6.6L V8 Diesel LB7 Engine ONLY**, and the other vehicles listed under Vehicle Fitment. The heat shield separates the filter from engine-bay heat so your engine pulls in cooler, denser air, while mandrel-bent aluminum piping and a high-flow, washable filter replace the restrictive factory air box for sharper throttle response.

The kit includes the mounting hardware, hoses, and couplers shown in the photos and installs using the factory mounting points.

• Increased airflow — a less restrictive design than the stock air box, for better throttle response throughout the rev range.
• Aggressive sound — a deeper, more pronounced intake growl every time you get on the throttle.
• Built to last — mandrel-bent aluminum piping paired with a high-flow, washable, reusable filter, engineered for a precise, secure fit.
• Complete kit — includes the mounting hardware, hoses, and couplers shown in the photos.
