A glow plug heats the combustion chamber in a diesel engine, providing the necessary temperature for fuel ignition, especially when the engine is cold.
Symptoms include hard starting in cold weather, rough idling until the engine warms up, and a glow plug warning light on the dashboard.
This NGK glow plug (Y1058J / 91821) is designed to replace OE number 19850-33020 and is listed for specific Toyota, Subaru, and Ssangyong diesel models. Always use a vehicle fitment tool or consult with us to confirm compatibility for your specific car.
The 11V rating indicates the operating voltage required for this specific glow plug to heat up effectively. Using a glow plug with the incorrect voltage can lead to poor performance or damage.
No, glow plugs are exclusively used in diesel engines. This part is not compatible with gasoline engines.
Typically, you will need a deep socket wrench or a specific glow plug socket, potentially a torque wrench for proper tightening, and possibly a wire brush or cleaning tool for the glow plug bore.
The lifespan of a glow plug can vary depending on engine use, operating conditions, and electrical system health. They are considered a wear item and may need replacement every 50,000 to 100,000 miles, or when symptoms of failure appear.
Check glow plug electrical connections for corrosion or looseness. Test glow plugs for continuity and resistance. Replace any faulty glow plugs.
One or more glow plugs may be weak or failing. This can lead to incomplete combustion until the engine warms up. Test and replace as necessary.
This indicates a potential issue with the glow plug system, which could include faulty glow plugs, a faulty relay, or wiring problems. Consult a mechanic for diagnosis.
Apply a penetrating oil and allow it to soak. Ensure the correct tool is used and attempt removal when the engine is slightly warm, but not hot. Over-tightening or forcing can break the plug.

Care:
Glow plugs are designed as wear-and-tear components and typically do not require user maintenance. Once installed, their performance is dependent on the engine's electrical system and fuel system. If starting issues arise, the glow plug should be tested and replaced if faulty, rather than attempting to clean or repair it.
