NOTE: See vehicle underhood emissions information decal for spark plug gap specification.

NOTE: If reusing originally installed spark plugs, reinstall them in original position. Some cylinders use platinum ground electrodes and some cylinders use platinum positive electrodes. Replacement platinum spark plugs are double platinum electrode spark plugs and are used for all cylinders.
