• Four yttrium enhanced ground electrodes resist spark plug wear and oxidation for exceptional performance life
• Fusion's voltage requirement increases less over time versus other iridium plugs for longer reliable performance of the vehicle's ignition system

• Factory-set gap ¿ once the proper gap is set, there's no need to re-gap
• Lower ignition voltage requirement provides reliable cold weather starting and superior operation under all driving conditions
• Tapered, yttrium enhanced v-profile ground electrode provides a 25% longer performance life

• Provides ease of installation - never requires adjustment
• Revolutionary surface air gap firing technology featuring four yttrium-enhanced ground electrodes delivers the longest, most powerful spark for ultimate engine performance
• Never requires gapping, the electrode gap is factory-set and never requires adjustment

• DiamondFire electrode technology that creates a superior spark and resulting flame front extending further into the cylinder, producing more localized pressure
• 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
