NGK 54181 spark plug wire set for the 1994-1995 Mercedes-Benz E420 V8 4.2L and other vehicles carries high-voltage current from the ignition to the spark plugs. It is one of the NGK spark plug wire sets built on a tinned copper core, made to OEM tolerances.
Misfires, a rough idle or hard starting can mean a cracked or burned wire. A worn spark plug or a weak ignition coil can be behind the same signs, so find the cause before buying. The set has eight wires with three coil leads, one per cylinder.
The 1994-1995 Mercedes-Benz S420 V8 4.2L and the 1994-1995 Mercedes-Benz S500 V8 5.0L are covered, along with other Mercedes-Benz models.
