The Classic Retrofit CDI+ 6 Pin unit is the direct replacement for Bosch CDI boxes fitted to classic Porsche 911 SC models from 1978 to 1983 on the SC and 930/911 Turbo to 1989.
Extensive development and rigorous dyno testing has proven the CR CDI+ unit to be a major improvement over the original Bosch CDI unit, with improved torque right across the rev range.
Classic Retrofit has now supplied more than 250 CDI+ units to very happy customers all over the world. The Classic Retrofit units are supplied with a lifetime warranty, subject to zero electrical abuse! Check out the online Porsche communities for the many great reviews of Classic Retrofit products - they are far superior to the cheaply made and overpriced, unreliable alternatives available elsewhere.
CDI ignition was originally fitted to a great many European sports cars of the 1970s and 1980s, including Maserati Ghibli, Alfa Romeo Montreal and are popular with BMW 3.0 CSL racers. The Classic Retrofit CDI+ is a great upgrade for all of these applications.
