The Classic Retrofit 8 pin CDI+ ignition unit is a direct replacement for the Bosch CDI units used in classic Porsche 911 RSR, 934, 935, 917, 962 and 930 from 1975 to 1977 . Extensive development and rigorous dyno testing has proven this CDI box to be a major improvement torque right across the rev range.

It is a little-known fact that the 8-pin CDI boxes provide better regulation over the output voltage than the 3- and 6-pin units. The by Classic Retrofit  redesigned electronic system brings the original voltage regulation concept bang up to date, not just by providing even better regulated output across all of our CDI units, but also by offering true dual-spark output at a 400us interval that truly makes a difference to combustion, right up to 10,000 RPM.
