Spark Plugs |

U-Groove Ground Electrode
Genuine Toyota Spark Plugs feature a U-Groove ground electrode which optimizes engine performance, including starting, acceleration, fuel economy and power. Because they do not have the U-Groove ground electrode, many non-genuine parts actually impair engine performance. |

Housing
Toyota uses reliable materials and precise construction methods to create its spark plug housings. The result is stable performance and long life. Genuine Toyota Spark Plug housings also have a high rate of thermal conduction, ensuring that they are always at the ideal temperature. Without proper heat conduction, spark plugs tend to run too hot or too cold, causing engine misfires or pre-ignition which often leads to engine damage. |

Heating Range
To work efficiently, engines must have spark plugs with the appropriate heating range. If the range is inappropriate, the plug may fail to ignite, resulting in poor starting, reduced performance on uphill climbs or when carrying a heavy load, and increased fuel consumption. A Genuine Toyota Spark Plug is the only way to guarantee proper heating range. |
