Used as an alternative to the now discontinued Bosch WR3CC, the NGK BR9ES uses 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
• Trivalent Metal Plating Provides Superior Anti-Corrosion and Anti-Seizing Properties
• Corrugated Ribs Prevent Flashover
• Pure Alumina Silicate Ceramic Insulator, Provides Superior Strength and Better Heat Transfer
• Triple Seals Prevent Leakage
