GMC Medium Duty 6500 Performance Air Intake - Wehrli - High Flow Intake Horn - Sparkle Copper - ‘19-’24. A direct bolt-on intake horn that replaces the restrictive OEM turbo inlet to improve airflow and response on 2019–2024 GMC 6500 trucks with the 6.6L Duramax L5D.

Crafted from CNC-machined, cast aluminum with an O-ring seal at the turbo, this true 4 in. inlet uses a smooth transition and an anti-surge face that mates to the compressor cover for consistent drivability. It includes a #10 ORB billet PCV barb and mounting hardware, requires no tuning, and works with OEM or aftermarket cold air intakes as well as stock or OEM-style drop-in turbochargers. Finished in Sparkle Copper and made in the USA.
