DENSO Auto Parts Spark Plug P/N:5384
DENSO Auto Parts 5027 spark plug for the 1992-1995 Ford F-250 V8 5.0L and other vehicles fires the spark that ignites the air-fuel mixture in each cylinder. It is an OE-grade plug.
Worn plugs can show up as hard starting, a rough idle or a misfire. Before you replace them, rule out ignition wiring and fuel delivery, which can also produce a misfire. Fit one plug per cylinder, so a V8 takes eight and the V6 3.8L takes six.
The 1979 Ford Mustang V8 5.0L, the 1980-1982 Mustang V8 4.2L and the 1983 Mustang V8 5.0L take this plug, as do many other vehicles. It is also a Chevy Impala spark plug for the 1980-1985 V6 3.8L. If your car is not named here, find its years and engine in the "Vehicles it fits" section.
