GMC Medium Duty 4500 Performance Air Intake by Wehrli Custom Fabrication – High Flow Intake Horn in Bengal Silver for 2019-2024. This direct-fit turbo inlet replaces the restrictive factory mouthpiece on L5D 6.6L Duramax trucks to improve airflow and throttle response.

CNC-machined cast aluminum with a true 4 in. inlet and a smooth anti-surge transition that mates to the compressor cover, this bolt-on upgrade increases efficiency over the OEM plastic part. It retains factory function with an integrated billet #10 ORB PCV connection, seals with an O-ring at the turbo face, and includes mounting hardware. The durable Bengal Silver powder coat resists the elements, and the horn works with stock trucks, OEM-style drop-in turbos, and OEM or many aftermarket cold air intake systems. Made in the USA.
