GENERAL INFORMATION
Check the ignition coil application to be sure it is being used in the prop-
er application for optimum performance.
Spark Plug Wires and Coil Wire:
To prevent false triggering and possibility of premature ignition failures,
use suppression type spark plug wire.
If your coil wire will not reach between the distributor cap and the igni-
tion coil, we suggest using one of the Mallory Spark Plug Wire
Replacement Kits. The Mallory Spark Plug Wire Replacement Kit is a 4
ft. length of 8mm Silicone Jacketed Suppression Wire assembled with a
straight spark plug boot and terminal on one end, and a 90° spark plug
boot and terminal on one end. Supplied with male (HEI), and female
socket type distributor boots and terminals that make these kits ideal for
remote mounting an ignition coil.
