Wehrli WCFab High Flow Intake Bundle Kit for 2020-2025 Silverado/Sierra 2500/3500 HD (L5P) - Candy Teal - WCF100410-CT

Fits select 2020-2025 Chevrolet Silverado and GMC Sierra 2500 HD/3500 HD models equipped with the 6.6L L5P Duramax diesel engine.

The WCFab High Flow Intake Bundle is a Stage 1 performance upgrade designed to eliminate restrictive factory components and common failure points in the L5P Duramax charging system. This kit replaces the narrow, multi-piece OEM intercooler plumbing with heavy-duty, one-piece mandrel-bent aluminum piping. By increasing the hot side to 3 inches and the cold side to 3.5 inches, this bundle reduces turbulence and improves airflow between the turbo and the engine for better throttle response and more efficient turbo spooling.

Engineered for durability under high-boost conditions, the driver-side (hot) pipe removes the failure-prone OEM resonator and middle boot joint. The passenger-side (cold) pipe features a CNC-machined flange with a double O-ring seal, replacing the factory plastic and rubber assembly that often leaks or fails under load. Finished in a signature Candy Teal powder coat, this bolt-on kit requires no ECU tuning and retains all factory sensor connection points.
