Tracy,   Where should I look for the SD10A / SD11A plugs that you use?   Are they NGK and is that the full number?  I am having trouble locating them.   Bill Eslick

Bill  I don't know how these stories get started.  The only plugs I have ever used are NGK brand  BUR 7EQ and BUR 9EQ.  Available at most autoparts stores.
