What's hot

• Significant potential power increase: > 6% to 12% (depending on engine class)
• Significant potential fuel efficiency improvement: > 4% to 13% (depending on engine class)
• Near elimination of performance inhibiting carbon deposits, dramatically longer plug life and a 5-year/100,000 mile limited warranty

• 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

• Multi-rib ceramic insulator to help prevent misfires
• More focused ignition for better flame kernel growth and faster fuel combustion for better engine performance
• Original Equipment (OE) form, fit and function five-year limited warranty

• Significant potential fuel efficiency improvement: > 4% to 13% (depending on engine class)
• Significant potential power increase: > 6% to 12% (depending on engine class)
• Drastic potential emissions reduction when used in 2 and 4-stroke engines (after 50 hours): 58% CO emissions reduction, 42% hydrocarbon reduction

• V-trimmed platinum sidewire electrode technology resists wear
• More focused ignition for better flame kernel growth and faster fuel combustion for better engine performance
• Original Equipment (OE) form, fit and function five-year limited warranty
