12v ignition coil - Remax, Viper, Bosch etc

[tscalfa]

Hi, I need to replace my ignition coil that is used with an electronic ignition system. I'm considering Viper, Remax and Bosch currently, such as the ones below. Does anyone have experience of these or any other recommendations?

Bosch ones are apparently not what the once were. I’ve been using Aldon Flame Thrower coils for 20 years, never had one fail.

I've been using Bosch for many years, including use in our own workshops and mail order and not had any problems.

I'm running 123 Electronic ignition and installed the recommended Bosch blue coil

Surely it's best to use whatever the ignition system is designed or optimised to work with?

Thanks for the responses so far. I'm leaning towards using an NGK one designed for electronic ignition as these seem popular among TVRs.

It's an Omex mappable ignition system that can be used with a range of coils rather than one specific coil as the coil dwell time can be adjusted to suit the coil. Prior to starting this thread I asked Omex if they had a recommended coil but they said any coil that provides a datasheet to establish the correct dwell settings.

If it is 123 distributor then the resistance across the low tension circuit is more important. Resistance must be more than 1.5ohm iirc, so a 3ohm coil is fine, but some are only 1ohm and will destroy the electronic distributor which is rather more expensive than any coil.
