Mercury Grand Marquis Spark Plug

Keeping your Grand Marquis in top shape is your top priority.

Select Your VehicleWhile it may not be difficult to find replacement parts for Mercury vehicles, these days the necessity for nothing but the absolute best are required to fix your car or truck. Anyone who operates a Mercury knows that when it comes to maintaining their vehicle only the absolute best replacement parts will do. You picked your Grand Marquis because its high-value and long-lasting quality appealed to your senses; so why would you settle for second best when it comes to the highest quality auto parts? The vehicle in your driveway is head and shoulders above the rest compared to all the other vehicles currently being driven today.

Why Spark Plug replacement is so important.

Sometimes the most important performance parts are the smallest, but they can be forgotten about when performing regular maintenance. The job of creating a spark in the combustion chambers that ignites the air/fuel mixture in the engine is your Mercury Grand Marquis spark plug. Basic spark plugs use a copper electrode, while performance spark plugs use platinum or iridium on all current models. Should a spark plug fail to do its job, the engine in your Mercury Grand Marquis will not turn as hard; leading to an increase in unburnt hydrocarbon emissions and a decrease in horsepower and fuel economy.

High quality parts, bargain prices, the best people.
