What's hot

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

• Increases fuel economy and lowers emission
• Built to OEM specifications
• Features trivalent metal plating which provide long lasting durability and protection against anti-seizing

• 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)
• Significant potential power increase: > 6% to 12% (depending on engine class)

• Stable combustion during idling
• Excellent acceleration and performance
• Features iridium with high melting point

• You can depend on NGK for quality and reliability
• Constructed from durable material
• Iridium alloy has extremely high melting point, perfect for today’s high-tech, high-performance engines
