(S)SPARK PLUG

The GM Performance 19307142 is a set of ACDelco Gold Double Platinum Spark Plugs. These plugs feature a double platinum point pad on both the center and ground electrodes for excellent durability and consistent voltage demands, which helps reduce wear on the ignition system. They also include a pure copper core for cooler electrode temperatures, maximizing durability and fouling resistance.

The one-piece, fired-in suppressor seal on these spark plugs blends three types of glass to create a gas-tight seal. This seal helps to reduce radio frequency and engine interference, regulate spark plug energy, and protect against compression pressures, contributing to a long service life.
