guys,
what would u think about the idea of insulating the OEM coils (with a heatshield wrap or sth) in order to avoid the excess heat on their
underside ??? ;-)

So the new Mounting Bracket does not expose the coils to the engine heat from below but allows for some air flow under the coils through this channel or groove.
I have a spare bracket coming from the US, and will post a pic if you want to see it...

Excellent info, Ash!
Regarding the 3 P/N. I guess there is the original P/N (no suffix), as per the original specs. Then the -A suffix is the later cost reduction exercice. Then finaly the -B suffix to quickly replace the crappy cost reduced part. I worked for Ford before (Engine Performance and Economy), so I've seenhow they do things.
