Mercury Custom Spark Plug Wires

Why you drive your Custom.

Your Mercury dealership isn't the only place to buy trusted replacement parts for your Custom. While it's not hard to buy replacement parts for Mercury vehicles, these days only the highest quality are required to fix your automobile. Mercury car, truck, or SUV owners have become used to a certain level of high-value when driving their Custom around town. When your Mercury Custom left the factory, it was destined for a driver who wants a trusted name in their automobile.

Don't go too long without fixing your Spark Plug Wires... here's why.

Without the properly working ignition timing system developed for the internal combustion engine, we would need an alternative like the turbine engines we find in jets. The fact that your Mercury Custom has mechanically or electronically timed ignition means that it needs spark plug wires. The current required to detonate the air/fuel mixture effectively is transferred from the engine control module (on newer vehicles) or distributor (on older vehicles) to the spark plug via your Mercury Custom spark plug wires. Sometimes called lead wires, these usually have a carbon fiber core wrapped in a fiberglass barrier, and covered with EPDM rubber for insulation from the heat in your engine.

We've got what you are looking for.
