Introducing the Chevrolet Duramax Performance Air Intake by Wehrli, the High Flow Bundle Kit Stage 1 in sleek Gloss Black, designed for the 2001-2004 6.6L Duramax. This premium kit replaces the restrictive OEM components to enhance your truck’s performance by optimizing airflow between the turbo and engine.

The Wehrli Stage 1 High Flow Intake Bundle improves your vehicle’s efficiency by upgrading the stock Y-bridge, passenger, and driver side intercooler pipes with 3" mandrel bent aluminum piping. This design significantly boosts throttle response and turbo spool up while reducing EGTs through a complete 3" intake tract, ensuring maximum durability and strength. Backed by high-quality silicone boots and a Fuel Pressure Regulator Valve (FPRV) Block Off Kit, this package is engineered to withstand increased pressures and temperatures, minimizing the risk of boost leaks.
