Are you looking for individual coils, either as a replacement or to build
an ignition system from scratch? Well, this is the place to find them. We
also include here the various coil driver modules that Holley offers.
This page also features the driver modules that allow the Holley ECU's
to control two-wire coils that are common on many Ford and Chrysler
applications. The Holley family of ECU's use a coil control method that
mirrors GM's HEI EST to trigger coils. This method will correctly drive
these 2-wire coils without the emplacement of a driver module between the ECU
and the coil.
