Know this is an old post, but wasn't around back in May. In my youth I had 2 Alfa' a 1971 Belina sedan and then a 74 spyder, I had Ansa systems put on to both cars, long term memory - they were great
sounded terrific, noticed a huge difference in performance, Alfa engines at the time were only 1750cc - the size of 2 size 10 shoe box's. 20 of my favorite cars - when they worked!
