I was on a vendor site over the weekend looking at glow plugs and certain plugs said do not use O.S. Plugs in Italian built engine Such as Novarossi, Top, RB etc, then other O.S. Plugs made no mention that they were not to be used in Italian engines. So I guess just to straighten this issue out....an O.S. Glowplug “can” be used in a Novarossi engine?
