What's hot

• 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
• Four yttrium enhanced ground electrodes resist spark plug wear and oxidation for exceptional performance life
• Factory pre-set gap allows for easy installation that never requires adjustment

• 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
• Four yttrium enhanced ground electrodes resist spark plug wear and oxidation for exceptional performance life

• Electrode gap is factory set to provide ease of installation - never requires adjustment
• Four yttrium-enhanced ground electrodes provide optimum access to the air/fuel mixture for the most efficient combustion, plus the yttrium alloy ground electrodes reduce gap wear and oxidation for extended performance life
• Provides ease of installation - never requires adjustment

• Full starting power at all times, even in cold weather, or with a lean fuel/air mixture
• Wider heat range for reliable stop and go driving
• Features a pure platinum center electrode that's heat-fused into an extended ceramic insulator to eliminate air gaps which exist in platinum alloy-tipped plugs

• 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
• Four yttrium enhanced ground electrodes resist spark plug wear and oxidation for exceptional performance life
