Im getting a old 1987 for Thunderbird running again after it sat for 12 years and I want to know what kind of spark plugs to get... I know it's probably has motorcraft coppers in it but would it hurt to put like a platinum or double platinum or e even a iridium for a one of the E3 plugs
A 1987 car came with a platinum plug? My '88 didn't have an owner's manual, so I didn't have anything to go by other than Advance Auto's recommendation (which may have just transitioned from Western Auto in 1995).
I concur, I had long been under the impression that Ford didn’t start using platinum plugs until they were using more powerful DIS ignition systems. Won’t hurt though.
