About this item

  • One-piece, fired-in suppressor seal blends three glass types for a gas-tight seal. Reduces radio frequency and engine interference, regulates spark plug energy and seals against compression pressures for long life
  • Double platinum point pad on center and ground electrode offer increased durability and consistent voltage demands to reduce wear on ignition system
  • 100% Pure Copper Core results in cooler electrode temperature for enhanced durability and superior fouling resistance

AC delco products are the choice for best results and consistent quality. GM vehicles should always use AC as correct plug rating and type originally came from the factory using this brand .

They are spark plugs. I don't know much else to say. Didn't expect dramatic results, but they seem to be performing as they should.
