What's hot

• 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
• 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 set pre-gap ensures ease of installation
• Bosch EXCLUSIVE tapered laser-welded platinum ground electrode provides more area for flame growth and increased durability
• 360° continuous laser welded center electrode provides unmatched resistance to thermal shock that can occur in today's high performance engines

• Electrode gap is factory set to provide 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
• 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

• Tapered, yttrium enhanced v-profile ground electrode provides a 25% longer performance life
• Contains one spark plug
• Exclusive platinum technology in the center electrode for quicker starts, smoother acceleration and increased fuel efficiency

• 360° continuous laser welded center electrode provides unmatched resistance to thermal shock that can occur in today's high performance engines
• Nickel plated housing provides superior resistance to corrosion and seizing
• 0.6mm ultra fine wire iridium center electrode provides exceptional ignitability
