I HAVE SOME BRAND NEW 1930'S CHAMPION SPARK PLUGS,THE NUMBER IS 15-A.DOES ANYONE KNOW WHAT THESE FIT.THEY ARE 18MM 7/8 HEX.
THANK YOU
I cross-referenced a Champion 15A at the autolite spark plug website and came up with this:
http://www.power-21.com/AutolitePower21i /PartDetailWindow.aspx?b=A&pn=386
It looks like it was a fairly common plug and was used in many cars, farm equipment, outboard boat motors, etc...
A similar plug is still availabe, but I think Champion has changed the numbers. (I think D16 or RD 16 are the replacement.) If you want to find out when they changed the part number, or if there is an old application chart for them you can contact Champion at their Website:

Michigan International Speedway- Brooklyn, MI August 19, 1990
you can go to a parts store and have them look up the code on it, and never throw away a spark plug, they are so much fun to play with, if you put them in a vice and hit the white ceramic part with a hammer it should break and that stuff is so much fun to play with, if you just flick it at a window it will shatter, it has something to do with the material. its made not to vibrate so i breaks stuff easily lol have fun
champion broke on me when i dropped it / Rj19lm for champion but is there a ngk for 19 heat range? 6hp
You can use any brand spark plug you want but make absolutely sure it is the correct heat range for that engine.
I already checked Champion spark plugs website and did a google search. Nothing worked out.
Post back what your looking for, what conversion and I might beable to help you
I want to convert my Harley Davidson plugs 6r12 to a Champion plug but can't find a book to do so
it's a 1999 883 sportster
Don't listen to chopperchopster. He builds choppers out of 350cc Hondas.
You can use a RA8HC or a QL16V S Champion plug.
Ride safe.

Champion Spark Plug Mine « Windyscotty's Blog
A very unique ghost town exists in the White Mountains near Bishop, California in the Eastern Sierra. What makes it most unusual is that it is on the honor system-nobody lives there and volunteers keep an eye on the place. Visitors are expected to be on their best behavior, but incidents of vandalism have occurred and buildings maliciously burned down. Yet, the old mining camp is still in great shape thanks to the efforts of people like Don and Margy Fraser, who worked hard to keep the camp alive.
The Spark Plug Mine is accessed off Hwy 6 about 20 miles north of the town of Bishop at the White Mountain Ranch Road. At the end of the pavement go left through a gate by the pump house. Travel down the tree line along the irrigation ditch for two tenths of a mile and hang a right on the road with another gate. This road is rocky and rough and requires four wheel drive toward the end. A quarter mile before the trailhead a scary four wheel drive road goes to an upper parking area that is only a mile walk from the site. The heat can make the lower trail a miserable experience in summer.
...Getting America back on track | Toledo Newspaper
Many of the persons who have written in to express their displeasure with my outlook on things have asked me my thoughts on what needs to be done to get America back on track. Apparently, after having trashed or pooh-poohed some of my sources as egghead, socialist, know nothing, academics, etc.etc, they would rather have someone with a high school diploma make all the pertinent commentary, which would explain their great admiration for Glenn Beck. I did go to college, but did not graduate, and did do a four-year electrical apprenticeship, so if that’s good enough for you, here goes.
The first thing that I would like to see done in order to turn our country and “guvmint” around is simple. We need to take money out of politics. Under our current system, most of our elected officials pay much more attention to the special interests with the large campaign donations than they do to the needs of the electorate that put them in office. Instead of doing what is in the best interest of the average working stiff, they pay much more attention to the needs of the corporate donors who feel the need to bleed us dry of every last cent to support their obscene salaries.
