Standard Ignition 7857 spark plug wire set for the 1998-1999 Cadillac Seville 4.6L and other vehicles carries ignition voltage to each spark plug through a conductive wire core inside a silicone jacket.
A misfire, rough running or hard starting can mean the wires are worn, and a cracked or rubbed-through jacket is a visible sign. Those symptoms alone do not prove the wires are the problem; a fouled spark plug is another common source.
This set is a direct-fit replacement for the 1998-1999 Cadillac Seville 4.6L and the 1995-1999 Oldsmobile Aurora 4.0L. It has eight leads, one per cylinder.
