Chevrolet Medium Duty 5500 Performance Air Intake – Wehrli High Flow Intake Horn, Sparkle Copper (2019-2024). This true 4 in. cast-aluminum turbo inlet replaces the restrictive factory mouthpiece to improve airflow and throttle response on L5D 6.6L Duramax trucks.

CNC machined and powder coated in Sparkle Copper, the horn features a smooth 4 in. transition with an anti-surge face that mates to the compressor cover. An O-ring at the turbo face, a #10 ORB billet PCV port, and included hardware support a reliable, clean install. It’s a bolt-on upgrade that needs no tuning, works with stock trucks, OEM or aftermarket cold air intakes, and drop-in turbochargers. Delivers 25% greater flow area at the compressor inlet and up to 27% better flow than stock. Replaces OEM 12678756 (GM 19432816, 12682569). Made in the USA.
