NGK 3210 spark plug for the 1950-1954 Pontiac Catalina 6-cylinder 3.9L or 8-cylinder 4.4L, the 1955 Catalina V8 4.7L, the 1956 Catalina V8 5.2L, the 1957 Catalina V8 5.7L, the 1958 Catalina V8 6.1L and other vehicles ignites the air-fuel mixture in each cylinder. Among NGK spark plugs, this Standard plug suits engines that run nickel alloy plugs; it is not recommended where precious metal plugs were fitted at the factory.
- NGK Standard line with a nickel alloy center electrode for consistent performance
- Solid copper core, 98% pure, for heat dissipation, conductivity and a wide heat range
- High grade alumina silicate ceramic insulator for dielectric performance
- Triple gasket sealing to prevent combustion gas leakage
- Trivalent metal plating for anti-corrosion and anti-seizing properties and easier installation and removal
- Cold-rolled threads that help prevent cross-threading and cylinder head damage
Quick facts
