GM Duramax LML CCV Upgrade Kit (2012–2016)

SKU DDACCCV11
Price

$142.99

Take charge of crankcase pressure and keep your intake system free from oily buildup with this CCV Upgrade Kit designed specifically for 2012–2016 LML Duramax trucks. The stock crankcase ventilation system often recirculates oily vapor back into the intake tract, leading to carbon deposits and diminished performance. This upgrade properly vents blowby gases, removes the bulky factory CCV box, and opens up valuable engine bay space—offering a cleaner, more efficient setup with a sleek appearance.

 

Key Features:

 

  • Effective Blowby Venting: Reduces crankcase pressure buildup, promoting healthier engine operation and enhanced performance.

  • Cleaner Intake Path: Prevents oil mist from contaminating your intercooler and intake piping, preserving airflow and throttle responsiveness.

  • Removes Factory CCV Box: Eliminates the OEM crankcase ventilation box, freeing space for easier maintenance and future upgrades.

  • Streamlined Hose Routing: Simplifies your engine bay with a clean, direct hose configuration.

  • Black Anodized Machined Aluminum: Durable plates with a refined black finish that both look great and withstand harsh conditions.

 

Why Upgrade Your CCV System?


On tuned or high-mileage LML trucks, crankcase pressure can cause excessive oil vapor to cycle through the turbo and intercooler, resulting in sludge buildup and reduced engine efficiency. This CCV Upgrade Kit tackles the problem at its source, improving airflow and ensuring your Duramax breathes cleaner and performs better over the long haul.

 

Compatibility:

 

  • Fits 2012–2016 GMC Sierra 2500HD/3500HD with 6.6L Duramax LML engine
