Plug Wire Set - Sierra Marine Engine Parts - 18-8821-1 (118-8821-1)

The spark plug wire transports a high-voltage current from the ignition coil to the spark plug. These wires are extensively insulated to keep the extremely high voltage current from escaping by arcing across the powerhead or any other grounded metal it can find. Any voltage loss along the spark plug wires results in a decrease of spark strength from the plug itself. Sea Star Solutions' plug wire set comprises eight spark plug wires and coil wire. It is the Thunderbolt Ignition Type, which is the most suitable for Mercruiser.
