What's hot

• Significant potential fuel efficiency improvement: > 4% to 13% (depending on engine class)
• Drastic potential emissions reduction when used in 2 and 4-stroke engines (after 50 hours): 58% CO emissions reduction, 42% hydrocarbon reduction
• Significant potential power increase: > 6% to 12% (depending on engine class)

• 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
• Fused iridium and platinum center electrode, sintered into an extended insulator nose results in reaching self-cleaning temperature only seconds after starting and provides exceptional wear resistance
• Fusion's voltage requirement increases less over time versus other iridium plugs for longer reliable performance of the vehicle's ignition system

• Reduces ignition system voltage requirements
• Features trivalent metal plating which provide long lasting durability and protection against anti-seizing
• You can depend on NGK for quality and reliability

• Low fuel consumption
