Doug C Posted August 20, 2019 Report Share Posted August 20, 2019 I am going to need to replace my spark in my 2007 Shelby GT. What suggestions as to what spark plug to use. Thanks - Doug Quote Link to comment Share on other sites More sharing options...
GTH391 Posted August 22, 2019 Report Share Posted August 22, 2019 I changed mine with the one piece Champion 7989. They cost a crap load more but I am not worried about the breakage issue. I also used anti-seize in the "neck" that extends down into the head. Keep any anti-seize off the electrode. Just smear it lightly on the extension.
