Dean3326 Posted July 5, 2016 Share Posted July 5, 2016 Spark plugs ? 1926 franklin model 11A engine E103545 can anyone tell me the type of spark plug that should be in this vehicle. It now has autolite 3095 with a reducer going from the 1/2 pipe thread of the spark plug to 3/4 pipe screwed into the head. Problem being the od of that reducer barely screws into the head maybe on 3 threads. so something is obviously wrong. What is the original spark plug and what is its thread dimensions. Also a source for technical information what should compression be? Thank you Link to comment Share on other sites More sharing options...
odyssey Posted July 6, 2016 Share Posted July 6, 2016 Hi Dean - Champion W-18 is the correct plug I think the new part number is 518. Your auto parts dealer can check the cross reference Tom Rasmussen Link to comment Share on other sites More sharing options...
Povertycove Posted July 6, 2016 Share Posted July 6, 2016 I use Autolite 3077's in my 11B. They seem to do really well. Link to comment Share on other sites More sharing options...
Guest newbymachineworks Posted July 6, 2016 Share Posted July 6, 2016 Autolite 3077 or 3076. 3077 are long reach, but have been discontinued. Have still been able to find them. Link to comment Share on other sites More sharing options...
ak Posted August 10, 2016 Share Posted August 10, 2016 Dutch Kern told me to use W14 as the W18 burns too hot. I have them in my car, and they have been in there for 40 years without any issue. Link to comment Share on other sites More sharing options...
147 Franklin Airman Posted September 5, 2016 Share Posted September 5, 2016 Hi AK When I first got my 11b it had Champion W16Y plugs in and I changed to W18 as the reach was slightly longer. They are burning quite nicely. I noticed that the W14 is a shorter reach. What issues did you have when using W18? Link to comment Share on other sites More sharing options...
putize Posted November 17, 2020 Share Posted November 17, 2020 Hi from Athens, Greece, S. Europe. Trying hard Europe wide to source ten (10) W18 (518) Spark Plugs for my Franklin 11-B (1927). I would appreciate any useful guidance. Yours, K.L.Zekakos, Dipl. Mechanical. Engineer 1 Link to comment Share on other sites More sharing options...
PFitz Posted November 17, 2020 Share Posted November 17, 2020 Hello, Putize. Have you tried searching online for any Champion Spark plug suppliers in Europe ? If you go to the Champion website and click near the upper left corner, it lists countries outside the USA that they deal with. https://www.championautoparts.com/Products/Spark-Plugs.html I don't see Greece listed, but it might be easier to order from a country closer to you than from here in the USA ? We can get the Champion 518 (old number W18) from many sources here is the USA such as our local autoparts stores. Or we can order them online from , www.amazon.com and www.rockauto.com . The online suppliers may ship internationally ? Paul Link to comment Share on other sites More sharing options...
putize Posted November 28, 2020 Share Posted November 28, 2020 I thank you for your comprehensive guidance. Yes., I have decided to reach sources European wise. Will definitely get back to you after my thorough search is fulfilled, since I believe that other European Franklin owners have met similar difficulties like mine. Yours Konstantinos.

mikewest Posted November 28, 2020 Share Posted November 28, 2020 Konstantios, Thats a fine looking Franklin! Im Curious, How many Franklins are in your area? Ive shipped 2 Franklins overseas... one to Germany and one to England. As I remember they were a 1930 147 sedan and a 1931 153 sedan. If you have problems getting the plugs , I can post them to you.

putize Posted December 17, 2020 Share Posted December 17, 2020 Dear Mikewest, At first I would like to thank you for your gentle approach. Here in my country (Hellas, South Europe), I'm proud to be the sole Franklin owner. It was my late father's favorite vehicle among 27 Historical Vehicles of our private Collection. I managed to source W18 Champions from U.K (so no custom fees will overcharge my package), but my Franklin has now W14 on it. Can you please advise which type should I finally order? The colder W14 (now installed on my Franklin) or the hotter W18 (suggested to me by fellow owners)? My technical knowledge on Franklin so far lead me to fit W14 on again, as they have cause no trouble for the last 25 years. But W18 still remain a vivid suggestion choice by American fellow Franklin owners, whom I always pay great attention to. Please do spare some time answer me W14 or W18, in order to result to my final order from U.K Market. I thank you in advance, Konstantinos.- Link to comment Share on other sites More sharing options...
