The NGK Spark Plugs BPR4ES-11 spark plug is engineered to provide dependable ignition performance for compatible gasoline engines. Designed with a copper core and precision-built components, this plug supports efficient heat removal, consistent combustion, and reliable engine operation. The BPR4ES-11 model is suitable for applications that specify this NGK replacement spark plug and should be matched to the engine manufacturer's fitment requirements.
Its trivalent metal plating helps resist corrosion and seizing, making installation and future service easier. A pure alumina silicate ceramic insulator delivers high strength and improved heat transfer, while triple sealing helps prevent combustion-gas leakage. Corrugated insulator ribs reduce the risk of flashover, supporting stable spark performance under demanding operating conditions.
Use the NGK Spark Plugs BPR4ES-11 when replacing a worn or fouled spark plug in a compatible engine. Confirm the vehicle or equipment application, thread specification, heat range, and gap requirements before installation. This product is identified by NGK manufacturer part number 4224 and vendor part number BPR4ES-11.
