NGK Standard Spark Plug BPR4ES (SOLID) - Box of 4 (1958-2019 Select Applications)

Fits select 1958-2019 vehicles from Chevrolet, Cadillac, American Motors, Bentley, Arctic Cat, and others.

NGK Standard spark plugs are engineered as high-reliability OE replacements, delivering consistent performance through proven materials and design. Each plug features a 98% pure copper core for superior heat dissipation and electrical conductivity, ensuring a wide heat range that prevents fouling and pre-ignition. The insulator is crafted from high-grade alumina silicate ceramic, providing the dielectric strength and physical durability needed to withstand extreme combustion chamber pressures.

To ensure long-term serviceability, these plugs are treated with trivalent metal plating, offering robust anti-corrosion and anti-seizing properties that make future removals easier. Triple gasket sealing prevents combustion gas leakage, maintaining engine compression and efficiency.
