Description
Overview:
The NGK BR8ES Spark Plug (MPN 5422) is a reliable, standard-fit spark plug for petrol engines used in powersport and utility machines. Built with a robust metal shell and high-grade ceramic insulator, it delivers a stable spark to ignite the air-fuel mixture for cleaner running and dependable starting. With a 14 mm thread size and gasket seat, it suits many ATVs and small engines where BR8ES is specified, including models such as Honda ATC250R-D and Kawasaki KLF300. The plug's resistor design helps reduce electrical interference with on-board electronics. Suitable for routine maintenance and repairs, it is sold individually, making it easy to replace plugs as needed during servicing or when addressing misfires, hard starting, or uneven idling.
