fi131, Do you mean the original marelli electronic ignition as fitted to later 131 supers etc, This will be an improvement from points but look in the distributor at the two wires that go to the electronic pick up as the insulation on these wires rots and can cause engine misfiring. The bosch electronic ignition is a lot better as doesnt suffer from this problem
The one i 've sourced has a brand new distributor I think it is a part that was fitted to later models and it fits all tc engines with the distributor at the block and even fits to push-rod engines.
I ;ve seen some sold through e-bay but i 've seen this set-up installed to Alfas as well .
What other improvements besides the points do you get from such a set-up?
Thanks
