Spark plugs for tuning

Choosing the right heat range in your spark plug is really important when enhancing the performance of a vehicle, otherwise it can come to overheating of the cylinder, or the spark plug keeps sooting up. A cold spark plug gives off more heat to the cylinder head, the electrode tends to soot because the cleaning temperature is not reached. A hot spark plug gives off less heat to the cylinder head, in this case the cylinder may overheat which can lead to piston seizure.

In addition to the heat value, thread length and diameter also play a decisive role when selecting a spark plug. A distinction is made between plugs with long thread plugs (E) and short thread plugs (H). Each cylinder head uses a specific type, so please double check before ordering.

Some guidance on the heat Range of NGK spark plugs

FYI - the higher the number, the colder the plug!

• Original cast iron cylinder => B7 or B8 (B8 for warmer climates)
  
  
• 50 cc and 70 cc Sport / Midrace cast iron cylinders => B8 or B9 (B9 for warmer climates)
  
  
• 50 cc and 70 cc aluminum midrace / racing cylinders => B9
  
  
• Engines with internal rotor ignition => the above plus 1 (Ex: 70cc aluminum racing cylinders + internal rotor ignition = B10)
  
  
• 70 cc and more high-end racing engines => B10
