High Flow Bundle Kit Stage 1 for 2020-2022 Duramax L5P Bengal Grey

Wehrli Custom Fabrication's Stage 1 Air Intake Bundle Kit significantly increases airflow between the turbo and engine, leading to improved efficiency, throttle response, and quicker turbo spool-up. This kit addresses and eliminates common weak points in the factory design that can cause boost leaks or outright failures in demanding high-performance situations. By replacing the OEM clip ring design at the Y-bridge connection with a robust silicone boot and stainless steel t-bolt clamps, it ensures a superior seal capable of holding higher boost pressures without leaks, thereby enhancing reliability and preventing blown factory boots and horsepower-robbling boost loss.

Crafted from 14-gauge aluminum, the kit features mandrel-bent smooth-flowing intercooler pipes and CNC-machined flanges with double o-rings for optimal fit and sealing. It includes a 3-inch driver (hot) side intercooler pipe, a 3.5-inch passenger (cold) side intercooler pipe, silicone boots, stainless t-bolt clamps, o-rings, and an intercooler outlet clip. The kit also offers custom color powder coating options to personalize the engine bay aesthetics. This product is designed for a straightforward installation, retaining factory connection points and sensors, and requires no additional tuning or modifications.

Installation of this kit is designed to be user-friendly, maintaining factory connection points and sensors, and does not require any additional tuning or other modifications. While specific tools are not listed, standard automotive tools for hose clamp and pipe removal/installation would be expected. Ensure proper alignment and tightening of all clamps to prevent boost leaks. This is a custom order part and cannot be canceled, returned, or refunded once processed. Also, please note that the manufacture, sale, offer for sale, or installation of this product is not legal in California.

This intake bundle kit is specifically compatible with 2020 through 2025 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD vehicles equipped with the L5P Duramax Diesel engine. It is not designed for other engine types or vehicle models. The kit offers a performance upgrade without compromising daily drivability or requiring extensive engine modifications.
