2020-2025 L5P Duramax Stage 1 High Flow Intake Bundle Kit

Stage 1 upgrade for the 2020-2025 L5P 6.6L Duramax Diesel Chevrolet Silverado or GMC Sierra 2500 / 3500 HD truck improves airflow between the turbo and engine for improved efficiency, throttle response, and turbo spool-up. Eliminates weak points in the factory design that can lead to boost leaks or complete failures in hard-working and high performance applications.

Kit replaces the restricted 2-piece 2.5 in. diameter driver (hot) side intercooler pipe and leak-prone plastic/rubber passenger (cold) side pipe with WCFab's heavy-duty three in. diameter 1-piece driver (hot) side and 3.5 in. diameter passenger (cold) side L5P Intercooler Pipes. Made in the USA from high strength, heavy duty 14 ga. aluminum tube with smooth, aerodynamic mandrel bends for increased durability and optimized flow. 3 in. 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. 3.5" 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 to increase reliability and eliminate blown factory boots and horsepower-robbing boost leaks. Full assembly is finished in your choice of WCFab's signature custom powder coat colors for a look as unique as your truck. Installs with basic hand tools. Compatible with stock trucks, no tuning required. Saves $25 vs. buying individually.
