Chevrolet Duramax Performance Air Intake - Wehrli 4in Intake Kit with Air Box, Bengal Red (2004.5-2005 LLY). Fabricated aluminum intake and air box that replace restrictive factory parts and feed your turbo cooler air.

Built with a 4 in aluminum tube and dry filter, this WCFab kit draws cold air from the inner fender to improve airflow, support power and throttle response, and help lower intake temps. Silicone boot, seals, and stainless T-bolt clamps provide a secure fit. The removable air box lid and included hydrophobic pre-filter make inspection and maintenance easy. Bolt-on install; no tuning. Made in USA.
