Dodge1934 Posted November 2, 2017 Share Posted November 2, 2017 I am looking for NOS AC plugs exactly like the one shown below. It is an early plug with wire electrodes and no number on the plug at all. Just the AC logo. it is a 7/8 plug with the extension below the threads. I am watching for NOS AC 78S plugs as well but that is not my main goal here. I am interested in 1 or a dozen what ever you have. let me know details and send pics of what you have.

Terry Wiegand Posted November 6, 2017 Share Posted November 6, 2017 These look like the old AC Titan plugs. The one on the left end is different from the other three. Terry Wiegand South Hutchinson, Kansas Link to comment Share on other sites More sharing options...

The one on the left end is different from the other three. Terry Wiegand South Hutchinson, Kansas The first two plugs are slightly different. The plug with the B will be from the 30`s when AC was using a lettering coding system. AC had changed to a number letter coding system sometime in the late 30s or early 40s. The earlier plugs had nothing printed on them to identify the use. I note the first plug is slightly different as well as the lower collar is round. It would be interesting to know what that was about. It could be as simple as a different production run or different production location. I would love to find a set that have "made in Canada" on them as my car is a Mclaughlin ( only made in Canada) yes I dream in colour..... But I did provide a fellow with a set of C4 champion plugs made in Canada a couple years ago so it can happen. Link to comment Share on other sites More sharing options...
Larry Schramm Posted November 10, 2017 Share Posted November 10, 2017 AC used to have a spark plug manufacturing plant in the UK. Do not know where in England, but that was at least in the 70's. Link to comment Share on other sites More sharing options...
