      Great product and used as a replacement for worn out components in a 2003 Focus. It had resolved a cylinder 4 misfire and allows easier starting.

            A:

            This Autolite Xp (Xtreme Performance) Iridium Enhanced Fine Wire Spark Plug (Part# XP5364) is not pre gapped. For your 2006 Mazda 3I, it should be adjusted to a spark plug gap of 0.051 inches. For any further assistance, please visit your nearest Advance Auto store or call us directly at 1-877-ADVANCE (238-2623) and one of our representatives there would be more than happy to assist you.

            A:

            A spark plug part number might fit hundreds of different engines from many different manufacturers. Although the spark plug from the 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. If adjusting the gap on fine wire or precious metal plugs such as platinum or iridium be very careful not to apply any pressure or prying force to the fine wire center electrode or insulator as they can be damaged. The gap should be adjusted by only moving the ground electrode.
            For compatibility of this part with your vehicle, please provide your vehicle make, model and engine specification.
