GMC Sierra 2500 HD Performance Air Intake - Wehrli - WCF Intake Kit - Flat Black - 2020-2025. A 4 inch high-flow aluminum intake and enclosed air box with a dry filter for 6.6L Duramax L5P trucks.

This WCFab system replaces the restrictive factory plastic tract, increasing airflow to the turbo for quicker response and cooler intake temps by drawing fresh air from the hood Ram Air duct and inner fender. Smooth 4 inch tubing supports strong velocity and adds a deeper engine and turbo note under acceleration. The 10 gauge aluminum box seals to the hood port and features a durable flat black powder coat. Installs with basic tools; no tuning required; works on stock trucks. Note: Disable the factory air filter monitor to avoid dash messages.
