Key Features:

• Laser Iridium Center Electrode
  The ultra-fine iridium tip ensures superior ignitability, providing a strong and consistent spark for improved throttle response and reduced risk of misfires.

• Platinum-Tipped Ground Electrode
  Minimizes electrode gap erosion, ensuring consistent performance over a very long service life and maintaining fuel efficiency.

• Optimized for Direct Injection Engines
  Specifically engineered to withstand the unique carbon fouling and pre-ignition challenges presented by gasoline direct injection (GDI) systems.

• Colder Heat Range
  The heat range of 8 is designed to dissipate heat more effectively, making it ideal for high-compression, turbocharged, and supercharged engines that generate higher operating temperatures.

• Longevity
  The combination of iridium and platinum materials offers an exceptionally long service interval, often matching or exceeding OEM recommendations.

• Improved Acceleration & Fuel Economy
  Enhanced combustion efficiency translates to more complete burning of the air-fuel mixture, which can contribute to better fuel economy and sharper acceleration.
