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
• 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

• Up to 12% more horsepower and torque allows for higher towing capacity and overall power
• Better throttle response, quicker ignition and improved cold starts
• Built-in capacitor element stores and delivers a much more powerful spark, providing for more complete combustion

• Up to 10% better fuel economy
• Built-in capacitor element stores and delivers a much more powerful spark, providing for more complete combustion
• Platinum tip ensures increased plug durability and a lifetime limited warranty

• Meets or Exceeds Original Equipment Design
• High Temperature, Pre-Greased Silicone Boots
• Increased Terminal Retention and Strength Properties

• Revolutionary surface air gap firing technology featuring four yttrium-enhanced ground electrodes delivers the longest, most powerful spark for ultimate engine performance
• Provides 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
