Chevrolet Silverado 2500HD Performance Air Intake - Wehrli - 4in with Air Box - Semi-Gloss Black (`06-`07). A high-flow, fabricated aluminum intake and enclosed air box that replaces restrictive factory components to let your LBZ breathe better.

Purpose-built for the 6.6L Duramax LBZ, this kit uses large 4-inch piping with smooth bends to improve airflow and help lower intake temps by drawing cold air from the inner fender. Expect crisper throttle response and a more pronounced turbo note. The dry filter and removable air box lid simplify inspection and service, while the included silicone boot, seals, and stainless T-bolt clamps provide a secure, durable install. Finished in Semi-Gloss Black powder coat. No tuning required; bolts on with basic hand tools. Made in the USA.
