Product Description This crankcase ventilation (CCV) assembly is designed to manage blow-by gases and stabilize crankcase pressure during engine operation. By separating oil from crankcase vapors, it helps reduce oil mist entering the intake system and supports proper ventilation under various driving conditions. The upgraded CCV design features an optimized internal structure that improves airflow and pressure release compared to earlier designs. This helps maintain more stable crankcase ventilation, especially as mileage increases or under higher engine loads. Manufactured from durable PA66 plastic, the housing provides reliable structural stability in engine bay environments. The unit is precision-molded based on original factory mounting points, ensuring accurate alignment and a direct-fit installation for compatible vehicles. This product uses a sensor-free design. For vehicles originally equipped with a CCV pressure sensor, installation may require clearing a fault code through a vehicle update, or transferring the original sensor if applicable. Compatibility should be confirmed prior to purchase.
