GMC Medium Duty 5500 Performance Air Intake - Wehrli High Flow Intake Horn - Flat Black (2019-2024). This bolt-on turbo inlet replaces the restrictive factory mouthpiece to improve airflow and sharpen throttle response on your 6.6L Duramax.

Engineered for 2019-2024 GMC 5500 trucks with the 6.6L Duramax (L5D), the CNC-machined cast aluminum horn uses a true 4 inch inlet with a smooth transition and an anti-surge face that properly engages the compressor cover for consistent drivability. An O-ring seal at the turbo, flat black powder coat, and a #10 ORB billet PCV connection deliver durable, leak-resistant performance. It installs with included hardware, works with OEM or aftermarket cold air intakes, and pairs with stock or OEM-style drop-in turbochargers. Made in the USA and requires no tuning.
