There has been much discussion here on the best plugs and wires to run. Now that the search feature is up again, you should try that. There's plenty of info on it. Some say Bosch +4 Platinum plugs are the best for mileage and performance, some have had problems with them though. I run Motorcraft in mine without any trouble. As far as wires, some here run Magnacore, Jacobs, and others. Your best bet is to try the search and see what you come up with.
