What's hot

• This provides space for the left hand thread remover to bite into the stainless steel plug tip so it can then be pulled
• Blow-molded storage case included
• Porcelain pusher is used to press the porcelain piece, without breaking the porcelain, farther into the plug tip

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

• 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 power increase: > 6% to 12% (depending on engine class)

• 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
• 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

• Increases fuel economy and lowers emission
• You can depend on NGK for quality and reliability
• Built to OEM specifications
