What's hot

• Exclusive platinum technology in the center electrode for quicker starts, smoother acceleration and increased fuel efficiency
• Tapered, yttrium enhanced v-profile ground electrode provides a 25% longer performance life
• Factory-set gap ¿ once the proper gap is set, there's no need to re-gap

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

• 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
• 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

• Multi-rib ceramic insulator to help prevent misfires
• V-trimmed platinum sidewire electrode technology resists wear
• Original Equipment (OE) form, fit and function five-year limited warranty

• Fine platinum tip reduces required voltage
• Constructed from durable material
• Extremely durable under high heat
