I have a few cars for which 123 makes ignition systems- 280SL, DS Citroen, E-type. I don't know anyone personally who has installed a 123 ignition system on their car, and if anyone here would like to provide feedback on installing one and how they feel about its performance, I'd be grateful to hear it. I should mention that the engines in the above cars are healthy and this may be a case of not fixing something that isn't broken. Mostly I would like to know if there are noticeable performance improvements with the 123 ignition in 113 cars. Thank you, in advance.
