This set of plug wires is of superior quality and fit perfect just like Ford installed at the factory. Replacing the old wiring is so easy and not like the poor quality cut to fit type that takes so much time to get just right. No muss and no fuss gets you are back on the road again quickly. The costs are so reasonable I am now able to afford to get my work in progress car collection up and running fast to attend local annual car shows driving my own classic cars a different one each time I go.
