genuine coils are £35 quid from ebay and also made by bosch all ford m k2 and 2.5 use bosch plugs coils and leads as standard at 1.3mm the foci had misfire and coil pack problems ford reduced the gap to 1.0mm and its never changed since for that very reason 1.2mm will not do much it may give a poor or a miss at idle as the gap will increase over time  given a bigger gap can eat coils in 10k miles youre figures are way out but if youre happy with 1.2mm go for it personally ive had the 1.3mm and it was a pain in the rear with misfires rough idle etc and yes bosch super plus are the plugs fords are just rebranded

Arthur, I appreciate your comments :) 

I'm going to give it a go with the 1.2mm gap, if I start having problems with idle etc, I'll take a look at the state of the plugs and maybe reduce the gap. At the moment it's sweet as a nut, but of course this could change. The Bosch plugs I put in looked very different to the Ford plugs that came out, god know how old there were as well maybe 3+ years, quite possibly the reason for the massive difference.

FYI My engine doesn't have the above coil pack, it has the individual coils like these:

My 2010 1.6 ti-vct focus had NGK TR5B-13 from the factory. Factory gap of 1.3mm on those plugs. I replaced with the same ones and have no issues with rough idle or misfires.

My coil pack is bosch. If you look on the various sites /catalogues for the Mk2's it shows a 1.0mm gap pre 2008 and a 1.3mm gap post 2008.
