NGK 4522 spark plug for the 1978-1979 Ski-Doo Everest 340 339cc and other vehicles fires the spark that ignites the air-fuel mixture in the cylinder. It is one of the NGK spark plugs in the Standard series, intended for engines with factory nickel alloy plugs rather than precious metal ones.
- NGK Standard series spark plug with a nickel alloy center electrode
- Trivalent metal plating with anti-corrosion and anti-seizing properties for easier installation and removal
- High grade alumina silicate ceramic insulator for dielectric performance
- Solid 98% pure copper core for heat dissipation, conductivity and wide heat ranges
- Cold-rolled threads that help prevent cross-threading and cylinder head damage
- Triple gasket sealing that helps prevent combustion gas leakage
Quick facts
- Part: NGK 4522 spark plug
- Fits: 1978-1979 Ski-Doo Everest 340 339cc and other vehicles
- Condition: New
A worn plug can show up as hard starting, a misfire or rough running, but coils, wires or fuel delivery can also lead to those symptoms, so trace the cause before replacing it. With the engine off and cool, a look at the electrode and ceramic insulator for wear, deposits or cracks is a good first check.
