It's not all the time that you discover you need a replacement Spark Plug to fix your automobile. The vehicle in your driveway is head and shoulders above the rest when it comes to all the cars, trucks, and SUVs in today's marketplace. Mercury automobile owners have grown accustomed to a certain level of reliability when driving their Grand Marquis around town. Make no mistake, you didn't buy your Grand Marquis unless you understood you would be getting performance and American style both rolled up into one vehicle.
Sometimes the most important performance parts are the smallest, but they are often overlooked. The job of detonating the air/fuel mixture in the combustion chambers 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. If one of the spark plugs wears out, 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.
