thanks u2 Posted by vvack0matic [Email] ![]() ![]() In Reply to: But vvack (happy xmas, BTW) the old plugs look, nicknick ![]() |
the old plugs look different because of the difference in operating temps they are subjected to. for the life of your old plugs they operated at normal operating temps for 3/4ths of their life with 1/4th of it boosting.
boosting will turn the plug white (lean mix) while driving normal and idling will char the plug slightly burning the white off the plug.
your new plug were subjected to boosting for 100% of their life.
