Update;
I've installed the wires along with a new set of Bosch Platinum +4 plugs (i know, people have opinions on THOSE too)
Anyway, the wires fit perfectly and appear to be of very sound quality. Installation took around two hours tops, most of which was taking breaks to have a snack or change the CD.
The truck is running much smoother than it had been with the worn stock wires and a set of very worn Champion plugs (it was definetely time for a new set).
So, so far I would recommend them after driving for about 20 miles (ha).
