MoTec CDI/8 Capacitor Discharge Ignition Module.
Only ever used to dyno V8 engines running coil on plug ignition system alongside an M8 ECU .
Never been in a car or exposed to the elements whatsoever . Grab a bargain as these are £1500 plus to buy new .
I also have an M8 ECU available which I can bundle in if required at a preferential price for the 2 items .
