NGK
Description
The NGK BR8HSA is a copper-core spark plug built for reliable ignition on 50cc scooters, ATVs, and small-displacement engines from KYMCO, Vento, and others. NGK's corrugated rib insulator prevents flashover, while the triple-sealed copper core aids heat removal and prevents interior leakage for consistent performance across a wide range of conditions.
