High Flow Bundle Kit Stage 3 for 2017-2019 Duramax L5P WCFab Grey

This kit is designed to improve airflow and performance for 2017-2019 Chevrolet L5P Duramax engines. It features a 4-inch turbo inlet, which, when combined with a Max Effort Tune, can result in a 25 HP gain. The kit includes high-quality hardware, silicone boot, seals, stainless steel t-bolt clamps, and a removable air box lid for easy maintenance of the WCFab filter. The filter includes a hydrophobic pre-filter cover to protect the MAF sensor, turbo, and engine. The ram air duct seal is repositioned to the bottom of the hood for a cleaner engine bay. The kit also upgrades restrictive factory intercooler pipes, replacing the 2-piece, resonator-equipped, 2.5-inch driver (hot) side intercooler pipe with a 3-inch diameter, 1-piece aluminum pipe, and replacing the leak-prone 2-piece plastic/rubber passenger (cold) side pipe with a 3.5-inch diameter, 1-piece aluminum pipe. Pipes are made in the USA from heavy-duty 14-gauge aluminum tube with smooth, aerodynamic mandrel bends for durability and optimized flow.
