123/B21-B23-R-V distributor for the Volvo B17, B19, B21, B23 and B230F engines

The 123/B21-B23-R-V is designed for the Volvo B17, B19, B21, B23 and B230F (not the B230E) engines, not only for classic cars like the Volvo 242, 244, 245 etc but also for the trucks and boats (Volvo Penta).
The 123 offers advance-curves for B17 - B25 Volvo & Volvo Penta engines including turbo engines. This is the result of thorough research in the original Volvo-workshop manuals. Even a couple of optimized LPG/Ethanol-curves are available.

Please note about the 123/B21-B23-R-V 123ignition

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 123 Blue Coil.

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.
