Spark Plugs

Good spark plugs that are in tip-top condition are needed in order to crank your car. They deliver an electric current from the ignition system to the combustion chamber of the engine. If your spark plugs are bad, however, your car will have trouble starting and you may notice decreased fuel economy and misfiring as well. They generally last a long time before they need to be changed out, but when you do need new ones, it is crucial to get them replaced. Find some of the best spark plugs available for your Porsche vehicle here, at Harper Auto Parts.
