Plymouth Roadrunner Spark Plug

Why you drive your Roadrunner.

The vehicle in your driveway is head and shoulders above the rest when it comes to all the vehicles in today's marketplace. While it may not be difficult to locate replacement parts for Plymouth vehicles, these days the necessity for nothing but the highest quality are required to repair your car or truck. Make no mistake, you bought your Roadrunner because you understood you would be getting a variety of special features and American style both rolled up into one automobile. It's not a regular occurrence that you find yourself in need of a replacement Spark Plug to fix your automobile.

What Spark Plug does for your vehicle.

Sometimes the most important performance parts are the smallest, but 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 Plymouth Roadrunner 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 Plymouth Roadrunner will not turn as hard; leading to an increase in unburnt hydrocarbon emissions and a decrease in horsepower and fuel economy.
