They work well in older cars with simple timing computers.

Comments about Autolite Copper Spark Plug:

Though copper plugs don't last as long as platinum, they run smoother in older cars that lack the sophisticated ignition timing computers of the newer cars. Might get rid of an annoying "check engine" light that would come on for no apparent reason.
