GMC Medium Duty 5500 Performance Air Intake - Wehrli - High Flow Intake Horn - Sparkle Copper - 2019-2024. Built for 5500 trucks with the L5D 6.6L Duramax, this cast-aluminum intake horn increases airflow to the turbo for sharper throttle response and reliable performance.

Wehrli’s true 4 in. inlet replaces the restrictive OEM plastic mouthpiece with a smooth transition and anti-surge face that keys into the compressor cover. CNC-machined, O-ring sealed, and finished in Sparkle Copper, it’s a bolt-on upgrade that needs no tuning. Compatible with stock and OEM-style drop-in turbochargers and with factory or aftermarket cold air intakes. Delivers 25% greater flow area at the compressor inlet and flows 27% better than stock. Includes a #10 ORB billet PCV connection and mounting hardware. Made in the USA.
