NGK 54309 spark plug wire set for the 1982-1985 Mercedes-Benz 380SL V8 3.8L and other vehicles carries high-voltage current from the ignition to the spark plugs. The insulation keeps that voltage inside the wire.
A misfire, rough running or a hard start can have several causes, and worn wires are one of them. With the engine off and cool, look along each wire and boot for cracks, burn marks or chafing before you decide they are the problem. If the wires are the cause, this set replaces them.
This NGK wire set is made for the 1982-1985 Mercedes-Benz 380SL V8 3.8L, the 1984-1985 Mercedes-Benz 380SE V8 3.8L and the 1982-1983 Mercedes-Benz 380SEC V8 3.8L, along with other vehicles. If your car is not one of these, look it up in the "Vehicles it fits" section.
