GMC Sierra 3500 Performance Air Intake – Wehrli 4in Intake Kit, Sparkle Copper, for 2006–2007 Duramax LBZ. A high-flow aluminum intake and air box that replaces restrictive factory parts.

This bolt-on system routes cold air from the inner fender through a large 4-inch tube with smooth bends to increase airflow, support power and throttle response, and help reduce intake temperatures. The sealed box houses a dry filter; the removable lid speeds inspections. Quality silicone, seals, and stainless T-bolt clamps deliver a durable fit and a deeper turbo note under throttle.
