Without being an automotive chemical engineer, there's no way to judge spark plug wires beyond whether you receive the right number in the pack and whether they fit and install properly. Maybe in five years that will change. But for now, these Prestolite plug wires do all that and just a little bit more. First, I liked the feel of the spark plug connector rubber. The connectors have to make a seal between the valve cover and the outside - keeping moisture and debris out. The rubber Prestolite uses is was firm but pliable and gave me confidence that the seal would hold up. Second, the package included a plastic envelope with dielectric grease to lubricate the rubber spark plug connectors. making installation a little easier. Third, the set included a coil wire, needed by earlier models of Geo/Sidekicks, but not my 1996. It made the set a little more versatile, which is okay by me.Read full review

These are factory OEM replacement coil packs. What else can I say? High quality and better than the cheap stuff that usually fails. These should last another 200,000 milles
