GMC Sierra 3500HD Performance Air Intake by Wehrli, 4in with Air Box in Semi-Gloss Black for 2006–2007 LBZ. This high-flow aluminum system replaces restrictive factory pieces to improve breathing and response.

Built for the 6.6L Duramax LBZ, the fabricated 4" tube and enclosed box pull cool air from the inner fender for steadier temps and quicker throttle. Smooth bends promote airflow and volume, while the dry filter and included hydrophobic pre-filter help keep the MAF, turbo, and intake tract clean. The removable lid simplifies inspection. Silicone couplers, stainless T-bolt clamps, and complete hardware support a straightforward, bolt-on install with basic tools; no tuning required. Finished in durable semi-gloss black powder coat.
