I have been doing all of the maintenance items recently and a tune up is next. The manual recommends replacing the plugs every 30,000 miles. I was thinking of putting in platinum plugs. Can anyone recommend plugs, wires, etc. I have heard some people have had problems not using OEM parts and wanted to avoid the problems. Thanks in advance.
