I going to change spark plug to my Fusion 1.6 Duratec 2009, did anybody have newest information gap size, Haynes says 1,3mm I found this info in internet, yes that is for Zetec engine, but is it possibele that it Applies to Duratec too? "Ford originally specified a plug gap of 1.3mm for the Zetec engine. However, this gap was found in practice to cause problems with coil pack and lead failures. As a result, Ford issued a TSB on this and reduced the gap from 1.3mm to 1.0mm, which appears to have solved the problems which were occurring."
