Re: triple fire plug, etc
Im with Meowy. There is only going to be one spark. I have friends who race dragsters and none of them use these style plugs, and they are trying to squeeze every .001 seconds out of their cars. Remember the old splitfire plugs that were popular in the 90's. The ones that claimed that they produced 2 sparks because of their 2 ground electrodes. That company discontinued them and only carry standard single electrode plugs now. Imagine that. I know they arent exactly the same as the triple plug but you get the idea. After you wear out the triple electrode one Id stick with the NGK. They are proven and easier to gap too.
