MSD Dual Ignition Tach Adapter for '03-07 Ford Focus 2.0/2.3L Duratec
Since 2003, the Ford Focus equipped with the Duratec engine has used coil-on-plug technology. When these engines are enhanced with turbos, superchargers, and nitrous, the need for a higher powered spark is necessary. The answer is to install an MSD DIS-4 Ignition Control. To get the proper operation from the new MSD DIS-4, 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.
