What's hot

• Fine Iridium tip ensures high durability
• You can depend on NGK for quality and reliability
• Constructed from durable material

• Nickel plated housing provides superior resistance to corrosion and seizing
• Factory set pre-gap ensures ease of installation
• Bosch EXCLUSIVE tapered laser-welded platinum ground electrode provides more area for flame growth and increased durability

• 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

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

• DiamondFire electrode technology that creates a superior spark and resulting flame front extending further into the cylinder, producing more localized pressure
• 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)
