Mercury Custom Spark Plug

Great cars and trucks like your Custom need great parts.

Mercury car, truck, or SUV owners have become used to a certain level of reliability when driving their Custom around town. Make no mistake, you didn't buy your Custom unless you knew that you wanted strength and American style both impeccably combined into one vehicle. Your Mercury dealership isn't the only place to buy trusted parts to repair your Custom. Auto enthusiasts know that a variety of special features is built into each Mercury, and know that only top quality repair Custom parts will suffice when your car or truck needs fixing.

Why Spark Plug replacement is so important.

There are ignition parts in your engine so small that they aren't considered when there's a performance problem. The job of detonating the air/fuel mixture in the combustion chambers in the engine is your Mercury Custom spark plug. Basic spark plugs use a copper electrode, while performance spark plugs use platinum or iridium on all current models. If one of the spark plugs wears out, the engine in your Mercury Custom will not turn as hard; leading to an increase in unburnt hydrocarbon emissions and a decrease in horsepower and fuel economy.

We've got what you are looking for.
