Our popular Spark Plug wire set for Magneto equipped Tractors equipped with the 116 or 125 BE or CE engines. These are made for the real early model Tractors like the model B,IB,C, & RC that had either the Fairbanks Morse "J" series Magneto (FMJ4B3) or the more improved "X" Mag. (FMX4B3) These models originally did not come with spark plug boots. Each of our wires are cut to length & numbered for each cylinder. Solid copper core wire tinned for corrosion protection. Top quality spark plug wire used!
