The Twin Power ignition amplifier incorporates both the CDI and transistor method ignition to provide optimum spark duration and maximum voltage output, resulting in crisper throttle response and a smoother engine powerband. Each DLI Type unit controls up to 6 individual coils for Direct Ignition Engines and multiple units can be used if needed for applications that use more than 6 coils. (CARB E.O. # D-186-29).
