GMC Sierra 2500HD Performance Air Intake by Wehrli, 4in Intake Kit with Air Box in Brizzle Blue for 2004.5-2005. High-flow aluminum intake and enclosed air box for the LLY 6.6L Duramax.

This WCFab kit replaces the restrictive factory plastic with a 4-inch aluminum pipe and dry filter, drawing cool inner-fender air to the turbo. The smooth, large-radius tract improves airflow and response and helps reduce intake temps. Silicone boots, stainless T-bolt clamps, and a removable lid simplify service. Hydrophobic pre-filter included. Bolt-on install; no tuning required.
