High Flow Bundle Kit Stage 1 for 2020-2022 Duramax L5P Candy Teal

This Stage 1 upgrade improves airflow between the turbo and engine for enhanced efficiency, throttle response, and turbo spool-up in 2020-2026 L5P 6.6L Duramax Diesel Chevrolet Silverado or GMC Sierra 2500/3500 HD trucks. It addresses weak points in the factory design that could cause boost leaks or failures in demanding applications. The kit replaces the restrictive 2-piece 2.5-inch diameter driver (hot) side intercooler pipe and the leak-prone plastic/rubber passenger (cold) side pipe with Wehrli Custom Fabrication's heavy-duty 3-inch diameter 1-piece driver (hot) side and 3.5-inch diameter passenger (cold) side L5P Intercooler Pipes. These pipes are made in the USA from high-strength, heavy-duty 14 gauge aluminum tubing with smooth, aerodynamic mandrel bends for increased durability and optimized flow. The 3-inch driver side pipe eliminates the OEM resonator and middle boot joint for improved flow and durability and includes high-quality reinforced silicone boots and stainless t-bolt clamps for superior temperature resistance and boost pressure holding capabilities. The 3.5-inch passenger side pipe features a CNC machined flange, black anodized CNC machined billet aluminum adapter with a double o-ring seal, and an upgraded silicone boot to withstand higher boost pressures than the factory components, increasing reliability and eliminating blown factory boots and horsepower-robbing boost leaks. The assembly is finished in your choice of WCFab's signature custom powder coat colors. It installs with basic hand tools, is compatible with stock trucks, and requires no tuning.
