High Flow Bundle Kit Stage 2 10-12 Cummins 6.7L Chevy Orange

The Wehrli Custom Fabrication Stage 2 High Flow Bundle Kit combines the Stage 1 High Flow Bundle and 4" Cold Air Intake Kit with Air Box. It increases airflow for the turbo and engine, improving efficiency, throttle response, and turbo spool up. It eliminates weak points in the factory design, preventing boost leaks and failures. The kit replaces restrictive factory pipes with heavy-duty, high-flowing 3" diameter hot side and 3.5" diameter cold side pipes. It includes upgraded high-quality silicone boots for increased reliability. Made in the USA from 14 gauge aluminum tube with mandrel bends. The fabricated aluminum intake pipe and air box enclosure with dry filter assembly replace restrictive plastic factory parts. This new design increases airflow, horsepower, torque, and provides quicker throttle response and cooler intake temperatures. Features 4" piping with smooth bends for improved air velocity and a more aggressive engine and turbo sound. Includes high-quality hardware, silicone boot, seals, and stainless steel t-bolt clamps. The removable air box lid allows for easy filter inspection and maintenance with an included hydrophobic pre-filter cover. Finished in WCFab's signature custom powder coat colors. Installs with basic hand tools. Compatible with stock trucks, no tuning required.
