NGK Racing Spark Plugs

NGK Racing Spark Plugs

NGK Racing plugs are the best plugs available for your rotary engine in a racing application. We do NOT recommend these for any kind of street use, regardless of the amount of power being made. 

These plugs are designed for racing engines that see a lot of heat and need a very cold plug as a result. They do not fire reliably at low rpm or when the engine is cold, and will foul quickly under these conditions. We often have to start our race cars with a set of stock plugs when cold then swap these in. 

For racing use they are outstanding and provide another layer of safety and increased power, the colder (higher number) plugs work better in extreme conditions such as high rpm, high boost pressure, etc. 

Price is per plug.
