      Distributor for 1972 Volvo 1800 ES

      Posted by Pierre Huard on Aug 14th 2025

      Great product, clear instructions except no mention of the fact that the tachometer will not function if you wire it according to the instructions.

      123 Distributor - 1973 Volvo 1800ES

      Posted by Matt Hall on Aug 16th 2021

      I had never changed a distributor out on a car before but the provided instructions made the process simple and easy. My car is running much smoother now and finally holds its' timing for more than a couple of days. Starting is much easy and the engine feels like it has new life. I can't recommend this product enough if you have an old distributor on points and condenser. I'm excited about not having to check gaps any more and know I have something I can set and forget. Thank you for keeping these old cars alive and well!

      Volvo 1800 distributor

      Posted by Paul Krimmer on Jun 2nd 2021

      Installation was easy. Once the timing was set all spark and fuel injector timing worked beautifully. Great product !

      The EASIEST install ever!

      Posted by Unknown on May 12th 2017

      I had to buy a more advantaged distributor for my Volvo P1800e with fuel injection. The 123 Ignition mated up perfectly! No more contact points, condenser, or trigger contact points to worry about. The time is set!
