About this item
- Iridium offers excellent engine idle stability and smooth performance
- Iridium allows for small, efficient electrode designs for reliable cold starting and quick acceleration
- Iridium fine-wire electrode helps burn away carbon deposits on the tip of the plug as they form
- One piece suppressor seal helps block radio frequencies that can affect vehicle electronics
- Suppressor seal meters spark energy for long electrode life and helps prevent combustion leakage
- Some ACDelco GM Original Equipment parts may have formerly appeared as GM Genuine Parts (OE) or ACDelco Professional
- ACDelco GM Original Equipment parts are designed, engineered and tested to rigorous standards, and are backed by General Motors
- GM Engineers design and validate OE parts specifically for your Chevrolet, Buick, GMC, or Cadillac vehicle
- GM regularly updates production and service part designs to integrate new materials and technologies
Platinum Spark Plugs
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
- 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
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
Conventional Spark Plugs
Designed with a high-quality copper core, these 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
- Available for use in marine applications
