NGK Motorbike Spark Plug DR8ES

The NGK Motorbike Spark Plug DR8ES use a central electrode with copper deeply inserted in the tip, quickly dissipates large amounts of heat, preventing overheating and fouling.

• Copper cored electrodes dissipates the heat combustion away from the firing end
• This prevents hot spots that can lead to pre-ignition
• It also has a longer insulator nose that can be used to protect against fouling
• Patented triple gasket sealing process eliminates the possibility of combustion gas leakage
• High alumina ceramics for better heat transfer and electrical insulation
