      MGB 123Ignition Electronic Distributor

      Posted by Kevin Keehn on Oct 21st 2025

      It’s my opinion that the Bluetooth Distributor by 123Ignition is the best. I have them on both of my cars and I wouldn’t use anything else.

      45D Bluetooth 123

      Posted by Unknown on Feb 5th 2024

      Just added this to my '79 Midget 1500. Setup was pretty easy and running great so far. Looking forward to some tuning when the weather improves. Also running a Holley Sniper 1100 EFI and it's working just fine with the 123 Distributor and 3ohm coil.

      Bluetooth 123

      Posted by Paul King on Apr 25th 2019

      I like this distributor a lot. I just got one for my MGA. Already have one on my MGB. It solved a problem on my MGA where the advance to let the engine start easily was way different for the advance for the best idle. I programmed the 123 and the problem disappeared.
