hmm.... I may be wrong but I'm pretty sure you can only get the proper spark plugs for a focus (zetec at least ) from the dealer..... I replaced mine twice now... and everytime I went to buy plugs, no other company except ford made plugs with the proper thread patern to fit in the head. And I did properly check.... this was no slack ass walk around crappy tire looking for plugs... this was a full search... plug manufacturer's web sites... phone calls... looking in manuals... the whole deal.... maybe I'm a retard thou.

and there is a maintenance interval for the wires. 40K. if you look in the ford service packages or whatever... the one with the full tune up.... it says change spark plug wires 40 000km. But what does ford know ? only tiny bits of info it seems.
