Contour Enthusiasts Group Archives Forums Modifications Duratec Performance Spark plug wires and Spark plugs

I installed the Bosch +4s in December and I was impressed with the smootheness of the engine at all RPMs. The mileage also got more consistant from tank to tank.

Last weekend I installed a set of Magnecor wires (BIG thanks to Joe at SPMotorsports!) and the engine was smoother running still. The bonus for me was that my install was halfway through a tank of gas and the nest itme I filled up and checked the mileage, it was about 1 mpg better. [I hope it stays that way!]

In summary, the wires and the plugs seem to be an excellent upgrade for the Duratech (I'll be checking how well they work on my wife's Mercury Villager as well; thanks again Joe Scott at SPMotorsports!).
