What's hot

• 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
• 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

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

• Multi-rib ceramic insulator to help prevent misfires
• Original Equipment (OE) form, fit and function five-year limited warranty
• V-trimmed platinum sidewire electrode technology resists wear

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

• Iridium-enhanced 6mm center finewire electrode for improved ignitability, durability and wear resistance
• More focused ignition for better flame kernel growth and faster fuel combustion for better engine performance
