The Classic Retrofit CDI+ 3 Pin is the direct replacement for Bosch CDI units used in the classic Porsche 911 from 1969 to 1977. 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.
More than 350 CDI+ units have been sold to very happy customers all over the world. These 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 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.
