Chevrolet Medium Duty 6500 Performance Air Intake — Wehrli High Flow Intake Horn, Bengal Silver (2019–2024). A true 4-inch cast-aluminum turbo inlet replacing the restrictive factory piece for cleaner, higher-volume airflow on L5D 6.6L Duramax trucks.

Built for the Medium Duty platform, this CNC-machined cast intake horn uses a smooth transition and anti-surge face to optimize compressor entry. It bolts on with no tuning, includes an O-ring seal, mounting hardware, and a billet #10 ORB PCV port, and the Bengal Silver powder coat adds durable protection. Compatible with stock and OEM-style drop-in turbos and works with most cold air intake systems. Made in the USA.
