Please note the following about the 123/B18-B20-R 123ignition

For electronic fuel injection-systems (where the engine needs a trigger pulse from the ignition) a 123/B18-B20-R-V-IE is available.

Please read the installation manual carefully. It contains more information on the motor- and distributor numbers, static timing and the advance-curves, the specifications of the 123ignition and a step-by-step description of the installation procedure.

Coil and spark plugs

Although used coils all look alike, they should be viewed with suspicion since one cannot tell from the outside whether, and how often they were exposed to overheating in the past. Installing the 123ignition system will ensure that the coil will never be overheated again in future. We recommend the 123 Blue Coil.

Perhaps you will also need new spark plugs? At 123ignitionshop we recently added the spark plugs most commonly used in combination with the 123ignitions we offer. See: the spark plugs list.
