Super 55 spark plugs

Anonymous-0 · Jun 2, 2014

What are you guys using for spark plugs these days. I have to replace the Bosch super ro 571 that are in it. Can't find them. I recently converted to 12v, I did see in a search here to go autolite 386. Looking for a 2014 on shelf plug for 12v anyway.
Thanks

We run 386 Autolites in all 6 of our Oliver gas tractors, doing hay. They run hot enough to keep fouling to a minimum, are reliable, relatively inexpensive, and easy to find/buy in town. Our 3 770's, 1 550 loader tractor, an 880 and a 1600 all use the same plug, so it is easy to keep them on hand as well. They usually last strong for at least 4 years if used regularly.
