What's hot

• Fusion's voltage requirement increases less over time versus other iridium plugs for longer reliable performance of the vehicle's ignition system
• Four yttrium enhanced ground electrodes resist spark plug wear and oxidation for exceptional performance life
• 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

• You can depend on NGK for quality and reliability
• Increases fuel economy and lowers emission
• Reduces ignition system voltage requirements

• 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)
• Near elimination of performance inhibiting carbon deposits, dramatically longer plug life and a 5-year/100,000 mile limited warranty

• Features superior anti-corrosion and anti-seizing properties
• Fine Iridium tip ensures high durability
• Constructed from durable material

• Four yttrium enhanced ground electrodes resist spark plug wear and oxidation for exceptional performance life
• Fusion's voltage requirement increases less over time versus other iridium plugs for longer reliable performance of the vehicle's ignition system
• 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
