NGK 4339 DCPR8E Standard Spark Plug - All Sea-Doo 4-TEC Engines

NGK Standard spark plugs are OE approved and recommended for reliable performance for most automotive and non-automotive applications. NGK Standard spark plugs feature a 5-Rib insulator design to prevent flashover and are also treated with corrosion-resistant plating to ensure ease of installation and removal. Cold rolled threads prevent damage to cylinder head. NGK's triple gasket sealing process virtually eliminates gas leakage past the shell. Solid Copper Core provides superior heat dissipation, conductivity and a broader heat range.

Key Features:

• Designed to operate over a much wider heat range than ordinary plugs
• Resists carbon buildup and pre-ignition
• High alumina ceramics for better heat transfer and electrical insulation
• Solid copper core and nickel tipped electrode provide a longer plus life
• Patented triple gasket sealing process eliminates the possibility of combustion gas leakage
• Solid copper core for greater spark
• Longer insulator nose prevents fouling
