What's hot

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

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

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

• Multi-rib ceramic insulator to help prevent misfires
• Iridium-enhanced 6mm center finewire electrode for improved ignitability, durability and wear resistance
