Duraspark

The Duraspark II is a triggering device for a Ford electronic ignition system. Coupled with either the stock ignition box or an aftermarket control box, it is a tough, readily available, reliable distributor.

Ford Motor Company began using electronic ignitions in 1973 with the Duraspark electronic ignition system and introduced the Duraspark II system in 1976. The biggest change, apart from the control box redesign, was the large distributor cap to handle the increased spark energy.

The system consists of a magnetic reluctor and pickup in the distributor, and an ignition module to trigger the coil. Typically, Duraspark II distributors have both mechanical and vacuum advance mechanisms.

The Duraspark II ignition system is a common upgrade for older Ford cars equipped with a points type ignition. In most cases the distributor will interchange with the older style points distributor.
