ACDelco GM OE (Professional) Iridium Spark Plugs are a high quality replacement ideal for many vehicles on the road today. They are the latest in spark plug technology and an exact replacement for your vehicle's original components. Iridium composition of the spark plug provides a high melting point and great strength, and provides excellent wear resistance and durability.

Features & Benefits:
  • 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
  • As spark plugs fire at an extremely high rate, these GM OE (Professional) Iridium Spark Plugs are under constant chemical, thermal, physical and electrical attack by corrosive gases that can reach upwards of 4,000 degrees Fahrenheit
