Strange spark plugs unknown HELP

I found a new set of 8 fire injector spark plugs part number L1 these are realy old. dose anyone know about these and or what they fit Thanks

 

pictures? sounds like something you'd buy from a full page "snake oil" type ad in a JC Whitney catalog

 

I think your right.
sounds like something i remember seeing in an old JC-W catalog my dad had.

 

Here are some

 

they look like aircraft plugs

 

They say [Run your car without ordinary spark plugs]

 

from the 1972 catalog rear inside cover....

 

i think you could get them from jc whitney back in the early 70 from the look of them my guess would be a chrysler product.

 

the long reach plug like that was used in small block Mopars and big block Chevys, a**** others.

 

you rule!
and definetly jared my memory

 

There have been so many ways to modify the basic spark plug design since the late 1890's that guys have all four walls of their garages covered with different types. When I got to 600 brands I knew I had a problem, and downsized to 100 keepers.

 

I'm pretty shure they were a 2 stroke gimmick, had some in an outboard a long time ago Check out rimfire on the web.

 

Thanks i like finding odd ball stuff

 

I know rotary mazdas use a plug that is similar to that.Strange **** is neat to find.

 

Many years ago I bought a box of C.R.A.P. (Cherished Relics And Posessions) at a swap meet. One of the items in the box was a can of spark plugs, with the name "REATH" (I'm guessing Joe Reath) on the side. They are Champion N-54R, N-57R, and N-60R plugs, with a very deep center electrode and a fixed-gap to a pin on the inside of the threaded portion of the plug. I ***ume these were used in one of his fuel cars.

Does anybody know if Joe is still with us? About a year ago there was a thread that said he'd been hospitalized, but never heard anything beyond that.
