High Flow Bundle Kit Stage 1 for 2020-2022 Duramax L5P Sparkle Granny Smith

The Wehrli 100410-SGS (WCF100410) is a Stage 1 High Flow Intake Bundle Kit designed for 2020-2026 L5P 6.6L Duramax Diesel Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks. This kit aims to improve airflow between the turbo and engine, leading to enhanced efficiency, throttle response, and quicker turbo spool-up. It addresses weak points in the factory design that can cause boost leaks or failures in demanding applications. The kit replaces the restrictive two-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 aluminum pipes. It includes a 3-inch diameter one-piece driver (hot) side and a 3.5-inch diameter passenger (cold) side L5P Intercooler Pipe. 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 removes the OEM resonator and middle boot joint for improved flow and durability, and comes with 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, a black anodized CNC machined billet aluminum adapter with a double O-ring seal, and an upgraded silicone boot to withstand higher boost pressures. The entire assembly is available in various custom powder coat colors. It is compatible with stock trucks and requires no tuning. Installation can be done with basic hand tools.
