Description

The WCFab Stage 1 upgrade for the 2011-2016 LML 6.6L Duramax Diesel Chevy Silverado or GMC Sierra 2500 / 3500 HD truck improves airflow between turbo and engine for improved efficiency, throttle response, and spool-up. It replaces restrictive OEM intercooler pipes and Y-bridge with larger, high-flow components, increasing total air flow by 33%. The kit includes upgraded silicone boots, incorporates the factory intake air heater grid, and features a billet resonator plate for enhanced engine sound and appearance. Compatible with stock trucks and OEM throttle valve/EGR controls.
