Chevrolet Silverado 2500HD Performance Air Intake – Wehrli WCFab 4" Intake Kit with Air Box, Fine Texture Black (2011–2016). This fabricated aluminum system replaces restrictive factory parts to increase airflow and sharpen throttle response.

Engineered for the 6.6L Duramax LML, the kit features a large 4" mandrel-bent intake tube and an enclosed aluminum air box that draws cool air from the inner fender. The high-flow dry filter and hydrophobic pre-filter help protect the MAF, turbo, and intake tract from contaminants. A removable lid makes inspection easy, while the Fine Texture Black powder coat offers a durable finish. Quality hardware, silicone boot, seals, and stainless T-bolt clamps are included. No tuning required; installs with basic hand tools.
