      A:

      With reference to your query on NGK Laser Platinum Spark Plug (PFR7H-10) - (Part No. 3978), a spark plug part number might fit hundreds of different engines from many different manufacturers. Although the spark plug from factory will come with a gap to a pre-selected setting, this may not be the right gap for your particular engine. The incorrect plug gap for your engine can contribute to a high rate of misfires, loss of power, plug fouling, poor fuel economy, and accelerated plug wear. It is always best to check the gap against the manufacturer's specifications. For compatibility, Please provide your vehicle make, model and engine specification. For any further assistance please feel free to call us at: 1-877-238-2623 or visit the nearest Advance Auto store and one of our representatives will gladly assist you with any questions or concerns you may have.
