5.“Copper plugs” “Copper spark plugs” is a term mistakenly used for a standard material spark plug. A standard material spark plug traditionally uses a nickel-alloy outer material fused to a copper core. Almost all spark plugs use a copper core center to conduct the electricity, jump the gap, and promote heat dissipation.
Back to O.E.M (original equipment manufactured). The four types of plugs are copper, platinum, double platinum, iridium. The type of ignition system should be your first variable to the question. Old ignition systems had one coil that provided spark to 8 plugs.
Platinum and iridium tips tend to last longer - copper tends to erode over time so the spark plugs wear out - plus they're slightly better conductors and can produce a spark under more adverse conditions (like under high cylinder pressures on turbocharged cars that run high boost).
NGK standard spark plug is manufactured to enhance the performance of any vehicle. It is constructed from durable materials that are corrosion and abrasion resistant. The spark plug insulators are made of 99 percent pure alumina silicate, allowing for longer insulator noses for reduced fouling.
Brisk Silver Racing spark plugs are suitable for standard, perfomance and racing applications, as well as CNG, LPG and E85 applications. 1) Name of series: Brisk Silver Racing spark plug 2) Spark plug intended use: All applications. It is the most versatile spark plug.
