Stage 1 High Flow Bundle Kit for 2025-2026 6.7L Cummins improves airflow between the turbo and the engine for improved efficiency, throttle response, and turbo spool-up. Eliminates weak points in the factory design - angled boots and plastic Driver / Cold Side Intercooler Pipe that can lead to boost leaks or complete failures in hard-working and high-performance applications. Replaces the poorly flowing factory 2.75" hot side and 3.25" cold side pipes with our heavy-duty, high-flow 3.5-inch-diameter pipes. The WCFab kit includes upgraded, high-quality silicone straight boots that withstand higher pressure and temperatures than OEM parts, increasing reliability and eliminating blown factory boots. Made in the USA from high-strength, heavy duty 14 ga. Aluminum tube with smooth, aerodynamic mandrel bends for increased durability and optimized flow. Full assembly 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.
