Champion Double Platinum 7304 plugs are a set of eight iridium-tipped spark plugs with a platinum pad on the ground electrode, aimed at long service life in many domestic and import engines. Champion is an OEM supplier, and the Double Platinum line is positioned above basic copper plugs for durability and steady idle quality. They suit owners doing a full tune-up who want a long change interval without moving to a full iridium plug. Compared with standard plugs they cost more but last longer; compared with premium iridium plugs they are a middle step.
