Standard Ignition V346 PCV Valve

PCV Valve for Nissan and INFINITI Applications

Standard Ignition V346 is a push-on PCV valve built for crankcase ventilation service on select Nissan and INFINITI vehicles. It uses a plastic body with a straight nipple and one 10 mm hose connection for direct replacement in the emission control system.

Compatible With 1997-2001 INFINITI Q45 and 1998-2001 Nissan Altima applications, this PCV valve supports proper crankcase vapor routing and helps maintain stable engine ventilation. The Standard Ignition V346 is a practical OE-style service part for common crankcase ventilation repairs.

Detailed Description

The Standard Ignition V346 PCV valve is designed for the crankcase ventilation system and is used to regulate the flow of blow-by vapors from the engine crankcase into the intake stream. On 1997-2001 INFINITI Q45 and 1998-2001 Nissan Altima models, a properly functioning PCV valve helps keep the ventilation circuit operating as intended and supports cleaner engine operation. If you are replacing a worn or restricted PCV valve, V346 provides the correct hose connection style and dimensions for the listed applications. This part cross-references PCV404 for the same application.

What It Helps Address

• Rough idle caused by restricted crankcase ventilation
• Excess crankcase pressure from a sticking PCV valve
• Oil vapor buildup in the intake system
• Vacuum leaks related to a deteriorated valve connection
• Emission control service needs on Nissan Altima and INFINITI Q45

Installation Notes and Tips

Verify hose size and connection style before installation. The push-on design and straight nipple orientation should match the existing routing on the vehicle. Inspect the hose for cracks, hardening, or looseness before installing the new valve, and confirm the inlet and outlet ends are seated securely after replacement. For fitment reference, this part fits 1997-2001 INFINITI Q45 and 1998-2001 Nissan Altima.

Quality Assurance

Standard Ignition supplies replacement emission control components for service applications, and V346 is built to match the listed fitment and connection requirements for the specified vehicles.
