BR8ES Spark Plug | NGK 5422

From the 1960s into the 2010s, many small engines came standard with NGK BR8ES nickel and copper spark plugs. NGK designed the BR8ES spark plug to fit any conventional application with superior performance versus other standard plugs because of their excellent conductivity and efficiency. They have a high-quality nickel alloy electrode, anti-fouling trivalent metal plating, a solid copper core and the company’s famed ceramic insulation technology. These materials allow the NGK 5422 to operate over a wide temperature range so you can brave hot summers and other extreme operation conditions. The plugs also have triple sealing on the gasket seat to prevent leakage.

NGK BR8ES plugs fit numerous boat and powersports engines from BMW, Yamaha, Honda, Suzuki, Husqvarna, Arctic Cat and other brands. To confirm fitment, check your manual to see if it lists the NGK 5422 or NGK BR8ES part number. Our knowledgeable sales associates can also answer compatibility questions. We sell the plugs as singles so you can buy the right amount for your power plant. They have a 60-day limited manufacturer’s warranty and ship fast from the nearest warehouse where we have them in stock.
