Premium™ Spark Plug - 0.625" Hex, 0.551" Thread Diameter, Flat Seat, 0.75" Reach
Push mower, Self Propelled Push mowers, Log splitters, Snow Throwers, Garden tractors, Riding Mowers, Commercial Riding Mowers, Generators, Sweepers, Stump Grinders, Wood Chippers, Presure Washers
The Champion Spark Plug is suited for small engines found in push mowers, riding mowers, snow throwers, and other outdoor power equipment that must start cleanly and run consistently despite short cycles. Its 14 mm configuration and fine-wire nickel center electrode focus spark energy efficiently, allowing easier ignition in engines that sit idle for extended periods or operate in cold, humid environments. The Heat Range 12 rating helps maintain stability through prolonged mowing sessions or generator run cycles, preventing fouling when conditions shift quickly. The Champion 71ECO also reduces emissions and contributes to smoother combustion, especially useful for equipment frequently restarting throughout the day.
