What's hot

• Drastic potential emissions reduction when used in 2 and 4-stroke engines (after 50 hours): 58% CO emissions reduction, 42% hydrocarbon reduction
• Significant potential fuel efficiency improvement: > 4% to 13% (depending on engine class)
• DiamondFire electrode technology that creates a superior spark and resulting flame front extending further into the cylinder, producing more localized pressure

• Four yttrium enhanced ground electrodes resist spark plug wear and oxidation for exceptional performance life
• Revolutionary surface air gap firing technology featuring Bosch's unique four ground electrode design delivers the most powerful spark for the most efficient combustion and optimum horsepower without increasing the voltage requirement
• Fusion's voltage requirement increases less over time versus other iridium plugs for longer reliable performance of the vehicle's ignition system

• Iridium alloy has extremely high melting point, perfect for today?s high-tech, high-performance engines
• You can depend on NGK for quality and reliability
• Fine Iridium tip ensures high durability
