DENSO Auto Parts Spark Plug P/N:5384
DENSO Auto Parts 5087 spark plug for the 1998-2003 Ford F-150 V8 5.4L and other vehicles fires the spark that ignites the air-fuel mixture in each cylinder. This iridium long-life plug is manufactured to the strictest OE performance, durability and emissions standards.
Hard starting, a misfire or a rough idle can mean a spark plug is worn, though an ignition coil or a fuel injector can be behind the same signs, so find the actual cause before you replace plugs.
This spark plug fits the 1998-2003 Ford F-150 V8 5.4L, which takes eight. For the 1989-1993 Ford Ranger 4-cylinder 2.3L it is one of eight spark plugs, and the 2006-2010 Ford Explorer V6 4.0L takes six. Driving something else? Look up your year, model and engine in the "Vehicles it fits" section.
