Dorman - HELP Coil Boot P/N:49818
Dorman 49816 spark plug boot for the 1997-2008 Ford F-150 V8 5.4L and other vehicles protects the coil-to-plug connection. This Dorman spark plug boot replaces one that has deteriorated or been damaged.
A cracked, torn or oil-soaked boot can go along with a misfire or rough running, though those signs have other causes too. With the engine off and cool, look the boot over for cracks, tears and oil soaking, and find out what caused the trouble before you replace it. This listing is one boot, and each spark plug position takes its own.
The vehicles it fits include the 2007-2008 Ford Mustang V8 5.4L and the 1997-1999 Ford F-250 V8 5.4L, along with many other Ford and Lincoln models.
