GM Duramax LML - CCV Upgrade Kit (2012–2016)
Take control of crankcase pressure and keep your intake system clean with this CCV Upgrade Kit for your 2012–2016 LML Duramax. The factory crankcase ventilation system is known to dump oily vapor back into the intake, leading to carbon buildup and reduced performance. This upgrade vents blowby properly, eliminates the bulky CCV box, and frees up valuable engine bay space—all while giving your setup a cleaner, more streamlined look.
Key Features:
- Vents Blowby Pressure: Helps reduce crankcase pressure buildup for better engine health and performance.
- Keeps Intake Tract Clean: Prevents oil mist from coating your intercooler and intake piping, preserving airflow and throttle response.
- Deletes Factory CCV Box: Removes the unsightly OEM crankcase box, opening up room for easier maintenance and upgrades.
- Streamlined Hose Routing: Simplifies your engine bay with a clean, direct hose setup.
- Black Anodized Plates: Machined aluminum with a sleek black finish—built to last and look sharp doing it.
Why Upgrade Your CCV System?
On tuned or high-mileage trucks, crankcase pressure can become a serious issue. The factory system recirculates this pressure—along with oil mist—back through your turbo and intercooler. That leads to sludge, reduced efficiency, and long-term reliability problems. This CCV Upgrade Kit fixes the problem at its source, giving your Duramax cleaner airflow and better breathing.
Compatibility:
- 2012, 2013, 2014, 2015, 2016 GMC Sierra 2500HD/3500HD 6.6L Duramax LML
- 2012, 2013, 2014, 2015, 2016 Chevy Silverado 2500HD/3500HD 6.6L Duramax LML
Cleaner Look. Cleaner Performance.
This CCV Upgrade Kit is designed for performance, reliability, and ease of install. With anodized hardware and improved routing, it’s a smart upgrade that pays off in both form and function.
