Is the champion x plug that the vendors sell, a correct plug for my 27 roadster? I run the two piece champions from Brattons Model A s in both of my Model A s. I want the plug that looks correct for my profile car. It has had auotlites in it for for several years. Thanks in advance for your information and advise. Tim
Of course there are many "correct" plugs from the period still around and usable...
