GMC Duramax Performance Air Intake - Wehrli - 4in Intake Kit with Air Box - Sparkle Copper - 2001-2004. A high-flow fabricated aluminum intake and enclosed air box for LB7 6.6L Duramax trucks, finished in Sparkle Copper.

This WCFab/Wehrli system replaces restrictive factory plastic with a 4 in intake tube, dry filter, and sealed box that draws cool air from the inner fender. Smooth, large-radius bends and greater volume increase airflow to the turbo for quicker response, cooler intake temps, and a bolder turbo note. Includes quality hardware, a silicone boot, seals, and stainless T-bolt clamps. No tuning required—bolt-on with basic hand tools. The removable lid and hydrophobic Outerwears pre-filter simplify inspection and help keep the MAF and turbo clean. Made in the USA.
