Spark Plugs: The Secret Behind the Spark

Watch how ACDelco small but strong spark plugs measure up to a massive Tesla coil.

Small But Mighty: Resilient and reliable, ACDelco Spark Plugs are designed to withstand the harsh elements of the engine. Inside the cylinder, spark plugs are subjected to severe conditions such as a 25,000 volts or more of electricity, temperatures reaching 4,000 degrees Fahrenheit, and pressure up to 2,000 psi. ACDelco Spark Plugs designed with iridium, platinum, or copper electrode (iridium shown); 100% copper core for cooler temperatures and enhanced durability; one-piece suppressor seal helps block radio frequencies that can affect vehicle electronics; and one piece ceramic insulator.
