GMC Duramax Performance Air Intake - Wehrli 4-inch Intake Kit + Air Box, Gun Metal (2004.5–2005 LLY). A high-flow, fabricated-aluminum upgrade that replaces restrictive factory parts on your 6.6L.

Built for the LLY, the 4-inch tube and enclosed air box pull cool inner-fender air to the turbo for better flow, faster response, and lower intake temps. Smooth aluminum bends aid velocity and a deeper turbo note. The dry filter with hydrophobic pre-filter helps keep the MAF and compressor clean. Silicone coupler, stainless T-bolt clamps, and complete hardware make installation easy. Made in the USA.
