Description
Overview:
The Genuine NGK Spark Plug BR10EG (Stock No. 3830) is a high-quality ignition component designed to deliver a clean, reliable spark in demanding engines. Built with a durable metal shell and a high-grade ceramic insulator, it withstands heat, vibration, and fuel contaminants for long service life. This plug features a 14mm thread with a 1.25mm pitch, a gasket seat for secure sealing, and a 19mm (3/4") reach to suit deeper cylinder heads. The 21mm (13/16") hex allows easy installation and removal with a standard socket. An integrated 5 kΩ resistor helps suppress electrical interference that can affect electronics. Suitable for many high-revving two-stroke engines and other petrol engines that specify this exact size and heat range, it supports smooth starting, steady running, and efficient combustion.
