Review on Motorcraft SP509 1840 EIGHT PCS SPARK PLUG MOTORCRAFT SP509 FORD EXPEDITION LINCOLN NAVIGATOR V8 by Chris Budenski

This is an original motorcycle spark plug. Old stubs with other fonts were made in Honduras until 2010. These spark plugs were assembled in Mexico City at the DF Ford plant. My Ford dealer stocked the exact same plugs with new fonts similar to those sold here at Revain. Folks, use proper anti-seize lubricant and torque ratio. These are great original candles! These are genuine Ford Motorcraft spark plugs. Use only Motorcraft commercial plugs and replace them every 95,000 miles in your 5.4 3V Trition.
