The Champion PowerSport 8809-1 Spark Plug gives your vehicle s engine the power it needs for proper operation. The fine wire projected electrode design delivers increased performance while also protecting against fouling. The V-trimmed ground electrode keeps the spark concentrated through all engine demands. A wire-wound low-ohm resistor and Q suppressor allow the full ignition energy to reach the cylinder where it is most needed. A thermal contour firing tip modifies heat transfer preventing deposits from building up from your vehicle idling. It also keeps the performance spark plug from overheating when the engine runs at high speeds. The plug is compatible with a variety of recreational sport vehicles.
