GMC Medium Duty 6500 Performance Air Intake - Wehrli - High Flow Intake Horn - Bengal Silver - 2019–2024. A cast‑aluminum, high‑flow turbo inlet for the 6.6L Duramax L5D that improves airflow and throttle response while retaining OEM fit.

This direct bolt‑on replaces the restrictive factory inlet at the compressor cover with a true 4 in. opening and a smooth anti‑surge face for optimized drivability. CNC‑machined cast construction with an O‑ring seal enhances durability, and the included #10 ORB billet barb simplifies PCV routing. Finished in Bengal Silver, it works with OEM and aftermarket cold air systems and compatible drop‑in turbos, with no tuning required.
