The NGK Spark Plugs ZFR4F-11 spark plug, manufacturer part number 4043, is designed to provide dependable ignition performance and consistent engine operation. This resistor-style spark plug uses a pure alumina silicate ceramic insulator for high strength, improved heat transfer, and reliable operation across demanding engine conditions. It is engineered for compatible automotive applications requiring the ZFR4F-11 model and should be selected according to the vehicle manufacturer’s specified spark plug requirements.
A copper core supports efficient heat removal, helping the plug maintain suitable operating temperatures during normal driving and heavier engine loads. Trivalent metal plating provides enhanced resistance to corrosion and seizing, supporting easier service and longer-lasting protection. Triple seals help prevent leakage, while corrugated insulator ribs help reduce the risk of electrical flashover for dependable ignition performance.
Verify vehicle, engine, thread, reach, heat range, and gap specifications before installation to ensure proper fitment. This NGK Spark Plugs ZFR4F-11 spark plug is intended as a direct replacement for applications that specify NGK part number 4043. Install using the vehicle or engine manufacturer’s recommended procedures and torque specifications.
