The NGK Spark Plugs BR8HSA Spark Plug is designed to deliver dependable ignition performance for compatible powersports and small-engine applications. This spark plug features an NGK heat range 8 rating and a compact design suited to engines that require the BR8HSA model. Always verify the recommended spark plug specification for your engine before installation to ensure proper fitment and performance.
Manufactured by NGK Spark Plugs, this replacement spark plug uses a copper core to aid heat removal and support stable operating temperatures. The pure alumina silicate ceramic insulator provides high strength and efficient heat transfer, while the trivalent metal plating helps resist corrosion and seizing for easier service and long-term durability. Triple seals help prevent leakage, and corrugated ribs reduce the risk of flashover for reliable ignition performance.
Fitment depends on the engine manufacturer’s specifications, including plug model, heat range, reach, and thread requirements. Confirm that the BR8HSA model and NGK manufacturer part number 5539 match your application before installation. The vendor part number is 5539.
