What's hot

• DiamondFire electrode technology that creates a superior spark and resulting flame front extending further into the cylinder, producing more localized pressure
• Near elimination of performance inhibiting carbon deposits, dramatically longer plug life and a 5-year/100,000 mile limited warranty
• Drastic potential emissions reduction when used in 2 and 4-stroke engines (after 50 hours): 58% CO emissions reduction, 42% hydrocarbon reduction

• 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)

• Long life and high reliability
• Stable combustion during idling
• Low fuel consumption

• 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
• Patented fused iridium and platinum center electrode, sintered into an extended insulator nose, provides exceptional wear resistance and reaches
