Genuine Briggs & Stratton spark plug designed for overhead valve engines. NGK triple gasket sealing reduces combustion leakage for cleaner emissions and steadier starts.
More reliable starts – thanks to resistance to carbon build-up and pre-ignition
Resistance to carbon build-up and pre-ignition reduces electrode fouling and the risk of misfires. Cleaner combustion surfaces help maintain a consistent spark under typical mowing loads.
More reliable ignition leads to quicker engine starts and fewer stalled attempts during yard work. Consistent starts save time and reduce the need for repeated pull starts.
Cleaner exhaust – with NGK's patented triple gasket sealing
Triple gasket sealing prevents combustion gases from leaking past the thread and seat, maintaining pressure where the spark occurs. Reduced leakage helps combustion remain efficient and lowers unburned exhaust emissions.
Cleaner-running combustion produces fewer exhaust fumes and steadier engine running at idle and under load. Improved sealing helps keep surrounding components cleaner and can aid emission checks.
Straight swap fitment – with genuine Briggs & Stratton part design
Designed as a genuine spare for overhead valve engines, the plug matches OEM dimensions and thread characteristics where specified. User reports confirm straightforward replacement in compatible mower engines.
Easy, direct replacement reduces time spent on repairs and allows DIY fitting for routine maintenance. Many owners avoid workshop labour costs by fitting the plug themselves.
