GM Duramax LML – CCV Upgrade Kit (2012–2016)

Protect the performance and longevity of your 2012-2016 LML Duramax with this CCV Upgrade Kit. The factory crankcase venting system often forces oil fumes back into the intake, leading to carbon deposits, airflow restriction, and reduced power efficiency. This upgrade is set up to manage crankcase pressure more effectively, keep your intake tract cleaner, and provide your engine bay with a streamlined, performance driven appearance.


  • Improved Crankcase Venting: By venting blowby pressure more efficiently, this kit reduces internal stress in your motor, enabling smoother operation and longevity in the long run.
  • Cleaner Intake System: Prevents oil mist contamination of your intercooler and intake pipe, helping to keep throttle response, airflow, and overall engine performance in check.
  • Simplified Engine Bay: Gets rid of cumbersome OEM CCV box, opening up space to allow easy access in normal maintenance or possible upgrade.
  • Optimized Hose Routing: Features a direct, straight hose design that improves airflow management in combination with under-hood organization.
  • Long-Lasting Construction: Anodized in glossy black, machined aluminum plates are robust, long-lasting, and provide a classy, elegant finish

Why Upgrade Your CCV System

As miles increase—which means added performance tuning—crankcase pressure gets more difficult to manage for the factory setup. Recirculating this pressure, plus oil vapor, back through your intercooler and turbo decreases component life, as well as efficiency. The CCV Upgrade Kit addresses this issue directly, so your Duramax enjoys cleaner flow, more stable power, and greater long-term durability.
