Champion Double Platinum plugs are a copper-core spark plug with platinum pads on both the center and ground electrodes, sold here as a six-pack. The double platinum design is built to hold its gap longer than a standard nickel plug, which suits older engines with hard-to-reach plugs like the 3.0L V6 in the 1988-1992 Eagle Premier. They are a stock-replacement part, not a performance upgrade, and they compete with platinum plugs from NGK, Bosch and ACDelco on longevity rather than spark output. Owners of aging vehicles pick them for a quiet, no-fuss tune-up that lasts.

Reception is generally positive among owners doing tune-ups on older cars, who report smooth idle and easy starting after fitting them. Complaints center on plugs arriving with the wrong gap or on suspected counterfeits.
