What's hot

• 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
• Factory pre-set gap allows for easy installation that never requires adjustment

• Significant potential fuel efficiency improvement: > 4% to 13% (depending on engine class)
• Significant potential power increase: > 6% to 12% (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

• Stable combustion during idling
• Excellent acceleration and performance
• Features iridium with high melting point

• You can depend on NGK for quality and reliability
• Features superior anti-corrosion and anti-seizing properties
• Iridium alloy has extremely high melting point, perfect for today?s high-tech, high-performance engines
