ACDelco Platinum Rapidfire® Spark Plugs are designed for everyday use and are a high quality replacement ideal for many vehicles on the road today. These spark plugs have high-quality suppressors that help prevent misfiring, an optimized plug to boot seal, and a pure copper core for great durability.

Features & Benefits:
  • Solid state suppressor, with two-piece glass and brass seal, can help reduce radio frequency interference, regulates spark energy for long electrode life, and helps 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 can reduce voltage requirements of the ignition system
  • Ribless insulator helps optimize plug to boot seal
  • Fits engines that run conventional plugs, as well as newer vehicles that require platinum plugs
