GMC Duramax LBZ Performance Air Intake by WCFab (Wehrli) – 4 in Cold Air, Deore Gold, 2006–2007. High-flow aluminum intake and air box replace restrictive factory parts for sharper response and a deeper turbo note.

Fabricated aluminum 4 in tube and enclosed box draw cool air from the inner fender, helping lower intake temps. Smooth bends boost air velocity and volume for improved throttle response and power. The dry filter includes a hydrophobic pre-filter, and a removable lid simplifies checks. Includes quality hardware, silicone boot, seals, and stainless T-bolt clamps. Deore Gold powder coat. Bolt-on; no tuning. Made in the USA.
