What's hot

• Drastic potential emissions reduction when used in 2 and 4-stroke engines (after 50 hours): 58% CO emissions reduction, 42% hydrocarbon reduction
• DiamondFire electrode technology that creates a superior spark and resulting flame front extending further into the cylinder, producing more localized pressure
• Significant potential fuel efficiency improvement: > 4% to 13% (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
• 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

• Four yttrium enhanced ground electrodes resist spark plug wear and oxidation for exceptional performance life
• 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

• Blade protector has thumb notch for easy blade removal
• Decimal and metric sizes laser etched on each blade
• Each blade contstructed fo hardened, tempered steel

• Features trivalent metal plating which provide long lasting durability and protection against anti-seizing
• Built to OEM specifications
• Increases fuel economy and lowers emission
