NGK NGK Standard Spark Plug P/N:6715
Bosch 6715 spark plug for the 1998-2003 Ford F-150 V6 4.2L and other vehicles ignites the fuel mixture in each cylinder. Its fine wire design with a platinum firing pin lasts up to 2 times longer than standard copper spark plugs.
Hard starting, a rough idle, a misfire or poorer fuel economy can mean worn plugs. A failing ignition coil can cause a misfire too, so a misfire alone does not prove the plugs are the problem.
The 1998-2003 Ford F-150 V6 4.2L, the 2005-2010 Ford Explorer V6 4.0L and the 2006-2011 Ford Ranger V6 4.0L are among the vehicles this spark plug fits, along with many other models. This listing is one plug, and the 1998-2003 Ford F-150 V6 4.2L takes six.
