In my racing engines we use spark plugs with no explosed electrodes, so that we do not have to gap and index the plugs, and also because they make massive power and great combustion....


So what's this about the new plugs with 4 exposed electrodes that are supposed to create "58%" less emissions...and better economy...You know...the plugs with green letters....


That has to be bull....58%....thats a crapload less....
