Wehrli Custom Fab High Flow Intake Bundle Kit for 2020-2025 Chevy/GMC 2500/3500 HD (L5P) - WCFab Red - WCF100410-RED

Fits select 2020-2025 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD (L5P Duramax).

The WCFab High Flow Intake Bundle Kit is a comprehensive Stage 1 upgrade engineered to optimize airflow between the turbo and the engine. By replacing the restrictive factory intercooler pipes, this kit improves turbo spool-up, throttle response, and overall efficiency while eliminating common failure points that lead to power-robbing boost leaks. This bolt-on system is compatible with stock trucks and requires no aftermarket tuning.

This kit replaces the undersized 2.5-inch OEM driver-side (hot side) pipe and the failure-prone plastic/rubber passenger-side (cold side) pipe. WCFab utilizes heavy-duty 14-gauge mandrel-bent aluminum for maximum durability under high boost. The 3-inch hot side pipe eliminates the factory resonator and middle boot joint, reducing turbulence. The 3.5-inch cold side pipe features a CNC-machined flange with a double O-ring seal, replacing the weak factory clip-ring design for a superior seal at the Y-bridge.
