Does anyone know the correct spark plug for the V8s engine?
At the rpi hompage they reccoment NGK BP6ES and at the NGK hompage for the engine B7ECS is recomended...
B7ECS is in at the moment - But I do have some BP6ES here - Have no idea what´s the difference and what happens if I use the others?

The goal is to get a plug that runs at the right temperature. Too cold and it won't self-clean. Too hot may lead to detonation or even a melted plug. You need to find the plug rating that produces the right temperature on your engine, and this will depend on all sorts of factors like compression ratio, mixture and ignition timing. Various sources recommend NGK BP6ES or NGK B7ECS for V8 wedges. NGK B7ECS is the recommended plug for the V8S onwards. The number indicates the heat rating of the plug (lower number = hotter).

If you want to know how to make sense of all the plug numbers, it's all explained here.
