ACDelco GM Original Equipment Double Platinum Spark Plug (Pack of 2)

Iridium Spark Plugs are engineered to offer excellent engine idling stability and a smooth performance. Iridium offers excellent engine idle stability and smooth performance. One-piece suppressor seal blocks radio frequencies that can affect vehicle electronics. Suppressor seal meters spark energy for long electrode life and seal against combustion leakage.

Platinum spark plugs are designed to deliver long-lasting performance and maximize durability. One-piece, fired-in suppressor seal blends three glass types for a gas-tight seal. It helps reduce radio frequency and engine interference, regulate spark plug energy, and seal against compression pressures for long life. Double platinum point pad on center and ground electrode offers durability and consistent voltage demands to help reduce wear on ignition system. Pure copper core results in cooler electrode temperature for durability and superior fouling resistance.

RAPIDFIRE spark plugs are made with ribless insulators to help optimize plug-to-boot seal. Solid-state suppressor with two-piece glass and brass seal helps reduce radio frequency interference, regulate spark energy for long electrode life, and protect against high combustion pressures. Pure copper core provides great heat transfer and helps maximize plug durability. Platinum on center electrode enables superior spark characteristics and helps reduce voltage requirements of the ignition system. Ribless insulator provides a great plug to boot seal.

Designed with a high-quality copper core, these conventional spark plugs help deliver reliable performance. Black onyx coating helps prevent corrosion. Copper core provides great heat transfer and helps maximize plug durability. Ribbed suppressor seal extends resistance and helps prevent spark "flash over" and misfires. Nickel-chrome alloy sheathing helps prevent corrosion on center electrode. These spark plugs are available for use in marine applications.

The one-piece, fired-in suppressor seal blends three glass types for a gas-tight seal that helps reduce radio frequency and engine interference, regulate spark plug energy, and protect against compression pressures for long life. The double platinum point pad on center and ground electrode offers excellent durability and consistent voltage demands to help reduce wear on ignition system. The pure copper core results in cooler electrode temperature for maximized durability and fouling resistance.

Some ACDelco GM Original Equipment parts may have formerly appeared as GM Genuine Parts (OE) or ACDelco Professional. GM engineers design and validate OE parts specifically for your Chevrolet, Buick, GMC, or Cadillac vehicle. Original equipment parts are designed to work with your GM vehicle safety systems -- aftermarket replacement parts may not meet the same OE safety regulations, depending on the part type. GM regularly updates production and service part designs to integrate new materials and technologies.
