NGK Spark Plug P/N:LFER7BHX
NGK PFR6T-10G spark plug for the 2002-2004 Jeep Grand Cherokee V8 4.7L and other vehicles fires the spark that ignites the air-fuel mixture in each cylinder. It is one of the NGK spark plugs engineered specifically for OE applications.
A rough idle or hard starting can mean the plugs are worn, though an ignition coil or a fuel injector can also be the source, so track down the cause before you replace anything.
The 2002-2004 Jeep Grand Cherokee V8 4.7L, the 2005-2007 Dodge Dakota V8 4.7L and the 2005-2011 Mercedes-Benz SLK55 AMG V8 5.5L take this plug, and so do many other vehicles. The count depends on the engine: one plug per cylinder on the V8 4.7L (eight in all) and sixteen on the V8 5.5L.
