Description:
The ACDelco Gold (Professional) RAPIDFIRE 19307141 Spark Plug is a premium aftermarket, OE-quality alternative designed for dependable everyday use. As a Single Platinum performance plug, it uses platinum on the center electrode to support strong spark characteristics and help reduce ignition voltage requirements. A pure copper core provides efficient heat transfer to support durability and consistent operation.
This spark plug features a solid state suppressor with a two-piece glass and brass seal to help reduce radio frequency interference, regulate spark energy for longer electrode life, and help protect against high combustion pressures. A ribless insulator design helps optimize the plug-to-boot seal. Built to meet fit, form, and function specifications for General Motors vehicles as well as most makes and models, it is part of the ACDelco Gold (Professional) line (some parts may have formerly appeared as ACDelco Professional).
