Chevrolet 6500 Performance Air Intake - Wehrli High Flow Intake Horn - Cat Yellow. A 4 in. cast-aluminum turbo inlet that replaces the restrictive OEM mouthpiece for quicker response and improved airflow.

Built for 2019-2024 Chevrolet 4500/5500/6500 with the 6.6L Duramax L5D, this CNC-machined casting uses a profiled anti-surge face and an O-ring seal to mate precisely to the compressor cover. It includes a #10 ORB billet PCV barb, works with stock trucks and OEM/aftermarket cold air intakes, accepts OEM-style drop-in turbos, installs as a bolt-on with no tuning, and arrives in durable Cat Yellow powder coat with mounting hardware. Made in the USA.
