I read it in a tech section on the WEB site.

If you add significant HP gains to your motor with more boost, you will need a colder plug in order to remove heat from the combustion chamber more efficiently.

If you run a plug that is too hot for your motor, you risk detonation under heavy loads (which is BAD). If you run a colder plug for your motor, the only risk is that the plug will foul quicker.

I personally would rather be changing fouled plugs more frequently, than running the risk of severe engine damage by running a plug that is borderline

I'm currently running W3CS plugs and they seem to be performing better in my motor than the W4CS plugs I had in there previously.
