I dunno,
but it seems to me that on the non svt duratec 2.5 like in citation's car, that the back plugs aren't as hard to get to, but I could be wrong. I know when I did mine on my SVT getting to the back plugs was a pain in the butt! In my opinion, a spark plug socket is a MUST! Also, a good pair of 90 degree needle nose pliers! Anyhow, let us know when you get it done!
