MSD Spark Plug Wire Set P/N:31389
MSD 31633 spark plug wire set for the 2010-2014 Ford F-150 V8 6.2L and other vehicles carries spark energy from the ignition system to each spark plug. The set is built to exceed OEM specifications and is sold as a direct-replacement wire set.
Misfires, hard starting or a rough idle can mean worn wires, though a failing spark plug or ignition coil can be behind the same signs, so find the cause before you replace anything. The V8 takes one wire per cylinder.
This set fits the 2010-2014 Ford F-150 V8 6.2L, the 2011-2015 Ford F-250 Super Duty V8 6.2L and the 2011-2015 Ford F-350 Super Duty V8 6.2L.
