Chevrolet Medium Duty 6500 Performance Air Intake - Wehrli - High Flow Intake Horn - Flat Black - 2019–2024. This cast-aluminum turbo inlet replaces the restrictive factory mouthpiece to increase airflow and sharpen throttle response.

Built for the 6.6L L5D Duramax, this true 4-inch horn uses a smooth transition and an anti-surge face that locks onto the compressor cover. CNC-machined cast aluminum and an O-ring seal deliver a precise fit and durability. It’s a direct bolt-on, includes hardware, and comes in a durable flat black powder coat.
