The 123/B21-B23-R is designed for the Volvo B17, B19, B21, B23 and B230F (not the B230E) engines and the Volvo Penta AQ151, AQ171 and AQ230 engines, not only for classic cars like the Volvo 242, 244, 245 etc but also for the trucks and boats (Volvo Penta).

If you want to tune your engine, we've got great news for you: this product is also available in a 123/TUNE version! Please read about the 123/TUNE-4-R-V-B21B23 here.

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 High Energy Coil 2020.

Perhaps you'll 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.
