NGK B7HS Copper Core Spark Plugs
Constructed from durable materials, these spark plugs boast corrosion and abrasion resistance, ensuring longevity and reliability. The insulators, made from 99 percent pure alumina silicate, feature extended noses for reduced fouling, promoting optimal engine performance. The triple gasket sealing process eliminates fuel leakage, while the solid copper core ensures superior heat dissipation and conductivity.
With a resistor produced from a glass and carbon mixture, fired for superior performance and durability, these spark plugs guarantee efficient ignition performance. The corrugated ribs prevent flashover, and the cold-rolled threads protect against damage to the cylinder head. Trust in NGK's commitment to excellence for spark plugs that deliver both reliability and enhanced engine efficiency.
