Upgrade airflow and cut under-hood heat soak with this Rtunes Racing heat shield cold air intake kit, built for the 2001-2004 Chevy Silverado 2500HD/3500 with 6.6L V8 Diesel Engine, 2001-2004 GMC Sierra 2500HD/3500 with 6.6L V8 Diesel Engine, and 2004 model year vehicles only fit with the LB7 engine type. Not all 2004 model year vehicles are equipped with the LB7 engine, so please check your VIN. The 8th digit of the VIN will be "1" on 2004 model year vehicles with the LB7 engine.. 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.

Available in Blue, Black, and Red. Pick your color above.
