cudaman Posted December 4, 2020 Share Posted December 4, 2020 Can anyone with a 1912 Flanders 20 tell me what spark plugs it uses? Is it 1/2" pipe thread like a Model T Ford, or something else? Thanks. Link to comment Share on other sites More sharing options...
Mark Shaw Posted December 6, 2020 Share Posted December 6, 2020 Yes, I expect it would be 1/2". Link to comment Share on other sites More sharing options...

Flivverking Posted December 9, 2020 Share Posted December 9, 2020 Go to your local E.M.F. automobile agency and they will help you. Just head out toward the center of town and trun right at 108 years ago. 1/2" pipe thread plugs are not hard to get..choices are limited. Most major brands still offer one or 2. Moodern common offerings off the top of my dull head. Champion 25 Autolite 3095 Motorcraft F11 Champion X. Classic take apart style period looking plug. There are others .

cudaman Posted December 9, 2020 Author Share Posted December 9, 2020 (edited) I got the car from the shipper a couple of days ago, looks like mine currently has Bethlehem "Five Point" spark plugs. I haven't removed one of them yet to see what threads and what reach it is. Edited December 9, 2020 by cudaman (see edit history) Link to comment Share on other sites More sharing options...
Dave39MD Posted December 9, 2020 Share Posted December 9, 2020 They look pretty good on the outside, maybe they will just need to be cleaned to get it running? Dave 1 Link to comment Share on other sites More sharing options...
JV Puleo Posted December 9, 2020 Share Posted December 9, 2020 Don't presume that all pipe thread plugs will work well. These early cars ran cold and need a hot plug with a long center electrode. You might be better off cleaning those plugs up and using them... 1 Link to comment Share on other sites More sharing options...
Flivverking Posted December 9, 2020 Share Posted December 9, 2020 How about this Auburn plug? Link to comment Share on other sites More sharing options...
cudaman Posted December 11, 2020 Author Share Posted December 11, 2020 Well, I pulled a plug on the Flanders 20 today and boy, did I get a surprise! It is indeed 1/2 inch pipe thread with a fairly short reach, but it has four ground electrodes surrounding the center electrode. From the color, it looks like the plug is firing well. It will certainly be a challenge finding more of these! Link to comment Share on other sites More sharing options...
Dodge1934 Posted December 16, 2020 Share Posted December 16, 2020 It can be a life long search looking for NOS originals checking out manufacturers literature can some times help determine what was original. When you find ones that work keep them and always be on the look out for more. Literature from 1912 is always challenging to find. good luck Link to comment Share on other sites More sharing options...
