Multi Power Spark Plugs

NGK Multi Power Spark Plugs feature multiple ground electrodes for extra-long life in a variety of applications.

Spark plugs wear out when the sharp edges of the ground electrode round off. Therefore, multiple ground electrodes provide additional surfaces for the spark to travel to, extending the plug's effective life.

Multi Power plugs are not for all applications, as they can tend to quench the spark, or hamper the ability of the flame to grow from the initial ignition point. However, the multiple ground electrode configuration can help alleviate a number of problems, including hard starting, excessive fouling or misfiring. They are also effective for vehicles with very high ignition system voltages and/or combustion chamber temperatures.

Typical applications for Multi Power spark plugs include factory turbocharged engines, Mazda rotary engines, and other high-compression type engines.

Remember that Multi Power spark plugs, or any other multiple electrode type spark plug, cannot provide more than one spark at a time. The primary purpose of the multiple electrode spark plug is to achieve greater spark plug durability and reliability over the life of the plug.
