What's hot

• 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
• 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

• Factory-set gap ¿ once the proper gap is set, there's no need to re-gap
• Exclusive platinum technology in the center electrode for quicker starts, smoother acceleration and increased fuel efficiency
• Lower ignition voltage requirement provides reliable cold weather starting and superior operation under all driving conditions

• More durability
• Improved fuel efficiency over the life of the plug
• Better performance

• 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)

• Nickel plated housing provides superior resistance to corrosion and seizing
• Bosch EXCLUSIVE tapered laser-welded platinum ground electrode provides more area for flame growth and increased durability
• 360° continuous laser welded center electrode provides unmatched resistance to thermal shock that can occur in today's high performance engines
