The Wehrli 20-24 Duramax L5P Stage 2 High Flow Bundle Kit - WCFab Grey is a comprehensive performance upgrade designed to enhance airflow and boost power for Duramax L5P engines from 2020 to 2024. Featuring a 4-inch turbo inlet that delivers a 25 horsepower gain when paired with a Max Effort Tune, this kit includes high-quality hardware such as silicone boots, seals, and stainless steel t-bolt clamps for durability and easy installation. The removable air box lid allows quick visual inspection and maintenance of the WCFab filter, which comes with a hydrophobic pre-filter cover to protect the MAF sensor, turbo, and engine airways from contaminants. The kit also replaces the restrictive OEM intercooler pipes with heavy-duty, mandrel-bent 14-gauge aluminum pipes—3 inches on the driver (hot) side and 3.5 inches on the passenger (cold) side—improving flow and reliability.

This Stage 2 High Flow Bundle Kit is specifically engineered for 2020–2024 Chevrolet and GMC Duramax L5P trucks, providing a direct bolt-on upgrade to the factory turbo inlet and intercooler piping. Ideal for street performance, towing, and daily driving, the kit addresses common OEM weaknesses such as the resonator-equipped, two-piece driver side pipe and the leak-prone plastic passenger side pipe. Installation is straightforward with included hardware and clamps, making it suitable for enthusiasts seeking enhanced durability and optimized airflow without extensive modifications. The kit’s components are proudly made in the USA, ensuring high build quality and long-term reliability.
