Chevrolet Duramax Performance Air Intake - Wehrli - 4in with Air Box - Illusion Purple - 01-04. Built for the 2001-2004 GM 6.6L Duramax LB7, this aluminum intake and air box improve airflow and response with an Illusion Purple finish.

Replace restrictive factory plastic with a fabricated 4-inch system that pulls cooler air from the inner fender. Smooth aluminum bends improve velocity and volume for crisper throttle and a stronger turbo note. The box houses a dry filter and a removable lid for fast checks; an included Outerwears pre-filter helps keep the MAF and turbo clean. A silicone coupler, seals, stainless T-bolt clamps, and full hardware provide a bolt-on install with basic tools. No tuning required. Made in the USA.
