• 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
• Fusion's voltage requirement increases less over time versus other iridium plugs for longer reliable performance of the vehicle's ignition system

• Significant potential fuel efficiency improvement: > 4% to 13% (depending on engine class)
• DiamondFire electrode technology that creates a superior spark and resulting flame front extending further into the cylinder, producing more localized pressure
• Significant potential power increase: > 6% to 12% (depending on engine class)

• 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
• V-trimmed platinum sidewire electrode technology resists wear
