Wehrli 20-24 Duramax L5P High Flow Intake Bundle Kit - Semi-Gloss Black

This Stage 1 upgrade improves airflow between the turbo and engine for the 2020-2026 L5P 6.6L Duramax Diesel Chevrolet Silverado or GMC Sierra 2500/3500 HD trucks. It replaces restricted 2-piece 2.5-inch driver (hot) side intercooler pipe and leak-prone plastic/rubber passenger (cold) side pipe with WCFab's heavy-duty 3-inch diameter 1-piece driver (hot) side and 3.5-inch diameter passenger (cold) side L5P Intercooler Pipes. It is made from high-strength, heavy-duty 14 gauge aluminum tube with smooth, aerodynamic mandrel bends. The 3-inch Driver Side pipe eliminates the OEM resonator and middle boot joint. It includes high-quality reinforced silicone boots and stainless t-bolt clamps. The 3.5-inch Passenger Side pipe features a CNC machined flange, black anodized billet aluminum adapter with a double o-ring seal, and an upgraded silicone boot. It retains factory connection points and sensors and requires no tuning.
