The 123/MG-4-R-V is designed specifically for the MGA and MGB, and is now also available with positive ground! All the advance-curves, that were EVER specified for these cars, are integrated into this product. In addition, there is a fine-tuned curve for the so called 'stage-two' engines too!

Static-timing is on TDC for all MGB-engines.

For a MGC please order a 123/GB-6-R-V.

The unit offers:

- Vacuum-advance
- Automatic dwell
- Automatic power-cut after 1 second
- Gear shift retard

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

Note: 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.

Indrukwekkende prestaties

Ik heb intussen 4 123's gekocht (voor verschillende auto's) en het systeem werkt perfect. Doordat je alles vernieuwt, ben je in één keer van de onderdelen met speling af. Inbouwen is een fluitje van een cent en daarna loopt de auto regelmatiger, is (iets) zuiniger en start VEEL beter.
