spark plugs

Hello,

 

On the webshop is mention about cold and warm spark plugs.  But it is never mentioned which type it is.  How can you tell the difference in order to buy the correct one?

 

Thanks

The numbers refer to the type of plug. In NGK for example, a B6 is hotter than a B7 and so on. The higher the number the cooler the plug.

If you search online, there are charts which show the different plugs.
