Wehrli Custom Fabrication High Flow Intake Bundle Kit – Candy Teal for 2020–2025 GM L5P Duramax (Silverado 2500/3500 & Sierra 2500/3500)
Upgrade the intake system on your 2020–2025 GM L5P Duramax with the Wehrli Custom Fabrication High Flow Intake Bundle Kit. This Stage 1 upgrade replaces the restrictive factory intercooler pipes with heavy-duty, mandrel-bent aluminum tubing for significantly improved airflow, throttle response, and turbo spool.
The kit includes a 3″ one-piece driver-side (hot) pipe that eliminates the restrictive resonator and middle boot joint, plus a larger 3.5″ passenger-side (cold) pipe with upgraded boots and a CNC-machined flange with double o-ring seal. Finished in striking Candy Teal powder coat, this bundle not only boosts performance but also adds a custom look under the hood.
