Introducing a revolutionary new product for classic cars including Porshe, Datsun, Mercedes, BMW and many British sports cars: the 123 electronic distributor! These distributors are designed as a direct replacement for your obsolete and usually non-functional original distributor and offers the advantage of having no mechanical advance mechanism, a CNC machined body and a universal high quality cap/rotor. Besides being extremely easy to install the 123 distributor offers flexibility to change ignition curves to suit your engine requirements. The basic model has sixteen built in advance curves that can be selected by simply changing a switch setting. More advanced models have the capability to change ignition curves using a USB computer connection or a Bluetooth connection to your phone, tablet or computer. The Bluetooth offers the most flexibility.
