Stage 1 High Flow Bundle Kit for 2019-2023 6.7 Cummins improves airflow between the turbo and 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, small diameter, crushed, factory pipes with our heavy duty, high flowing 3.5” Diameter Pipes. The stock passenger / hot side pipe is only 2.75 inches in diameter and a significant restriction in the intercooler system. The WCFab kit includes upgraded high quality silicone straight boots that withstand higher pressure and temperatures than the OEM parts to increase reliability and eliminate 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.
