Take control of your 2017–2025 Duramax L5P with our CCV (Crankcase Ventilation) Upgrade Kit, designed to improve engine reliability and keep your intake system clean. The factory CCV system is known for allowing oil vapors to re-enter the intake tract, which leads to carbon buildup, reduced efficiency, and long-term maintenance issues. Our upgrade kit solves this by rerouting crankcase gases safely, preventing oily residue from coating your intercooler and intake system.
