Dual Ignition Adapter Ford Coil-On-Plug

Since 1999, the Ford Modular Motor has used coil-on-plug technology. As enthusiasts hot rodded these engines with turbos and nitrous, the need for a higher powered spark became apparent. The answer is to install two MSD DIS-4 Ignition Controls.
To get the proper operation from the new Ignition Controls, you will need two of these Ignition Adapters. They modify the trigger signal so all of the features on the car operate while the ignition receives the inputs it needs to fire the system.
