The DPR8EA-9 SPARK PLUG (86-4929) fits to function in a considerably broader temperature range than regular plugs. They have a high resistance to carbon accumulation and pre-ignition. High alumina ceramics for each to improve heat transfer and electrical insulation. A revolutionary triple gasket sealing method prevents combustion gas leakage, while a longer insulator nose keeps fouling and misfiring at bay. The longer extra life is due to the robust copper core and nickel-tipped electrode. The corrosion-resistant coating of NGK Standard Spark Plugs ensures simplicity of installation and removal. The 98 percent pure copper core allows for more efficient heat dissipation, resulting in more reliable starters and a lower danger of overheating.
