Thanks Tabetha, that's what I thought too . What I have heard is that when using bad sparkplugs or HT leads the high voltage would damage the inside of the Focus coilpack. Something that I have never heard about the old Zetec ones.

So now I made up the Focus bracket so that it can have the old zetec coilpack. Bloody hard to do... The best thing you can do is find yourself a old zetec bracket. At this both old and new coilpacks will fit!
