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.

Learn how to properly attach new spark plug terminals and boots by reading our tech article. How to Install Spark Plug Wire Ends.

 

Wire Looms

Polished stainless steel tubes accommodate wires up to 7 mm. Attaches to intake manifold of 1949-1953 flathead Ford V8's. Will not work with oil fill/vent tube on '49-'53 engines without modification.
