More info

The 123/MG-4-R-V is designed specifically for the MGA and MGB, both only negative 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
- Spark balancing
- 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 Bosch 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.

Bon produit

Good item, easy to fit and easy to adjust, what I appreciate also :
- strength of the spark, associated with the Bosch Blue coil
- and also : speedness, information and support from 123Ignitionshop

At last a reliable replacement!

My wife has owner her 1972 MGB for 37 years and at last we can feel confident that not only will it start easily, but will also keep going!
Easy to fit and looks original, but shows how much car electronics has improved over the years.
I have no hesitation in recommending 123ignitionshop, their service was faultless, rather like their product.

very good product

Since installing the 123 ignition system in my 1971 MG B, the car is performing very well. The power has increased, the economy has improved, the car starts first time, there is no overheating, and no 'running on'. The new electronic ignition, which my son and I fitted from the very clear instructions, has given new heart to the old car, and it feels much more robust, but still retaining the character of the MG. Thank you LEEN APK, I would definately reccomend this product to other classic car ownwers
