Not all vehicles are alike. Different engines require different spark plugs that specifically operate under certain heat ranges. Therefore, having spark plugs that properly fit an application is essential.
Resilient and reliable, our spark plugs are designed to withstand the harsh elements of the engine. Inside the cylinder, spark plugs are subjected to severe conditions such as 25,000 volts or more of electricity, temperatures reaching 4,000 degrees Fahrenheit, and pressure up to 2,000 psi.
Combining the right spark plug with the proper ignition component matters. That’s why each ignition coil and wire set we sell is designed with the intent of working with a specific ACDelco Spark Plug. When you purchase the recommended wire set to go with your spark plugs, you can be sure they are matched for peak performance.
The boot is designed for a watertight seal when paired with the correct ACDelco Spark Plug.
The high-temperature silicone jacket resists heat, oil, and abrasion.
