911 1969-77 CDI+ 3 Pin Ignition Spark Box Classic Retrofit

The CDI+ 3 Pin is Classic Retrofit's direct replacement for Bosch CDI units used in the classic Porsche 911 from 1969 to 1977. Extensive development and rigorous dyno testing has proven our CDI+ unit to be major improvement over the original Bosch CDI box. The Classic Retrofit CDI+ unit requires no modifications to the original wiring loom harness or metalwork and is 'plug and play'. Our custom aluminium casing sits perfectly in your engine bay for a very attractive appearance. All Porsche 911 CDI+ units have a 48 MHz microprocessor onboard to control ignition timing.
