NGK 6884 spark plug for the 2023-2025 Sherco 450 Sef Factory 449cc and other vehicles fires the spark that ignites the fuel and air in a cylinder. Like other NGK spark plugs in the Standard line, it is engineered for OE applications.
- NGK Standard line plug with a nickel alloy center electrode for consistent performance
- Trivalent metal plating resists corrosion and seizing, which helps installation and removal
- High grade alumina silicate ceramic insulator for dielectric performance
- Triple gasket sealing to prevent combustion gas leakage
- Solid 98% pure copper core for heat dissipation, conductivity and ultra wide heat ranges
- Cold-rolled threads that guard against cross-threading and cylinder head damage
Quick facts
- Part: NGK 6884 spark plug
- Fits: 2023-2025 Sherco 450 Sef Factory 449cc and other vehicles
- Condition: New
A worn plug can show up as hard starting, a misfire or rough running. The ignition or fuel system can cause the same symptoms, so trace the cause before buying plugs. With the engine off and cool, a pulled plug with a cracked insulator, worn-down electrodes or a gap outside spec is ready to be replaced.
Fits
The same plug also fits the 2023-2025 Sherco 500 Sef Factory 478cc and the 2021-2024 Triumph Speed Triple 1200 RS 1160cc. This listing is one plug, and the count follows the cylinders: one per cylinder, so the Sherco takes one and the Triumph takes three. If your machine isn't named here, look up its year and engine in the "Vehicles it fits" section before you order. The plug is best suited to engines with OE nickel alloy plugs and is not recommended where the factory plug is precious metal.
