Spark plugs in engine tuning
The correct spark plug temperature is important for engine tuning, otherwise the cylinder can overheat or the spark plug will burn out continuously. A cold spark plug emits more heat into the cylinder head, and the electrode tends to become fouled with soot because the cleaning temperature isn't reached.
A hot spark plug emits less heat to the cylinder head; in this case, care must be taken because the cylinder can overheat, with the risk of the piston seizing.
In addition to calorific value, the length and diameter of the thread also play a decisive role in choosing a spark plug. A distinction is made between spark plugs with long threads (E) and short threads (H). Each cylinder head uses a specific type, so it's advisable to double check before ordering.
Here is a guide to the thermal value of NGK spark plugs
By the way: the higher the number, the colder the plug!
- original cast iron cylinder => B7 or B8 (B8 for warmer climates)
- 50cc and 70cc Sport / Midrace cast iron cylinders => B8 or B9 (B9 for warmer climates)
- 50cc and 70cc aluminum midrace/stroke cylinders => B9
- Engines with internal rotor ignition => the above plus 1 (e.g. 70cc aluminum racing cylinders + internal rotor ignition = B10)
- high-end racing engines of 70cc and above => B10
