NGK 1097 spark plug for the 1996-2000 Yamaha G11-A Yamahauler and other vehicles fires the spark that ignites the fuel mixture in the cylinder. Like other NGK spark plugs in the Standard line, it suits vehicles that run nickel alloy plugs, not those with factory precious metal plugs.
- NGK Standard line plug with a nickel alloy center electrode

- High grade alumina silicate ceramic insulator for dielectric performance
- Solid 98% pure copper core for heat dissipation and conductivity
- Cold-rolled threads that prevent cross-threading and damage to cylinder heads
- Triple gasket sealing that prevents combustion gas leakage
