What It Helps Address

• Excess crankcase pressure
• Oil vapor buildup in the crankcase ventilation system
• Rough idle caused by a restricted PCV valve
• Oil contamination from poor ventilation flow
• Emission control issues related to crankcase breathing

Installation Notes and Tips

Verify the thread size, connector style, and hose connection before installation. This V399 valve uses a screw-in design and does not include a gasket, cap, or connector, so the existing vehicle setup should be inspected for wear or damage before replacement. Confirm exact fitment by year, make, and model before ordering.

Quality Assurance

Standard Ignition supplies replacement emission control components for service applications, and V399 is listed with direct interchange references for the same vehicle coverage. Use the confirmed fitment data to match the part to the correct Nissan or INFINITI application.
