Ignition Coil

The hotter the spark, the easier your engine will start, and this 40,000 volt coil is just the ticket to a quick start! Its higher voltage allows larger spark plug gaps for added power, smoother response and better fuel economy. These coils are internally resisted so they are compatible with many inductive ignition systems.  

  • Smooth chrome finish 
  • 40,000 volts
  • For use with 12 volt inductive ignition systems.
  • 1.5 Ohm primary resistance
  • Legal in all 50 states and Canada


Spark Plug Wires

Finally, a set of 7mm supression spark plug cables as a universal plug wire kit for your Flathead.

We started with black, 7mm suppressive core wire that will go through your looms. The 90° black plug boots are installed but you have to install the straight or 90° distributor ends. We even put in enough wire to place your coil on the firewall. Comes with straight boots for the distributor end of the plug wire. Black only.

Two sets of boots/terminals are included, one set for conventional socket-type caps and one set for HEI type caps. The set includes 9 cables, the longest being 51" and the shortest being 24". Use eight for the plugs, one for the coil.
