New unused spark plug. No original packaging. Power Boost Firing End. Fine- wire projected electrode design delivers more power and maximum fouling protection. V-trimmed ground electrode keeps spark concentrated through all engine demands. Q Suppressor Wirewound low ohm resistor enables full ignition energy to reach the cylinder where its needed most. Thermal Contour Firing Tip. Modifies electrode heat transfer to prevent deposits while idling and plug overheating during high- speed operation.
