Motorcraft Finewire Platinum-Tip Spark Plug

The quality, performance, reliability, and confidence of the Motorcraft name is available in spark plugs for a broad range of applications, including domestic and imported cars and all sizes of trucks. Motorcraft spark plugs are the only ones designed, engineered, and recommended by Ford Motor Company. Whatever the application, Motorcraft offers a spark plug that fits. The same premium-quality spark plugs that have 100,000-mile replacement intervals and are used in many new Ford Motor Company vehicles are available as replacement plugs for earlier-model vehicles. Platinum's high melting point provides superior resistance to erosion. This results in 60,000 to 100,000-mile intervals between spark plug changes, while maintaining optimum engine performance.

Rated 4 out of 5 by from Only plugs for 06 Expedition Can't really use anything else... Price is pretty good for the plugs. They are expensive, but a new truck is over 50k. Have over 300k on the truck & plane on many more miles.
