Chevrolet Duramax Performance Air Intake - Wehrli - Illusion Purple - `04-`05. Built for 2004.5–2005 GM Duramax LLY 6.6L trucks, this 4-inch intake and air box replace restrictive factory parts to improve flow and throttle response.

WCFab’s fabricated aluminum pipework and enclosed air box draw cooler air from the inner fender for lower intake temps and sharper response. Large-radius 4-inch tubing preserves velocity and volume, while the dry filter with hydrophobic pre-filter helps keep the MAF and turbo clean. Quality silicone coupler, stainless T-bolt clamps, and a removable lid aid service. Finished in Illusion Purple powder coat. Bolt-on with basic tools; no tuning required. Made in the USA.
