Sparkie Plugs
Having just serviced the S6 this morning, why is it that the spark plugs are never ever tight when you come to get them out. I do check them periodically but they always seem loose to me i.e. Just undo without any force at all or are even loose. Why, is it the the fact that the sparkplugs are steel and the head is alloy??
