Product Description
Perma-Tune basic ignition control module for BMW 3.0CS and 3.0CSi models from 1971-74. The basic model performs the same functions as the analog modules did back in the day. For the average street car, this may be all that is desired and of course is more affordable than the Premium model. It is however still a high performance part and is perfect for racing venues that do not allow programmable digital ignition systems. The Basic model has a smooth, more original looking housing than the Gen 5 cast housing.
