Double Platinum Spark Plug

The ACDelco GM Original Equipment Double Platinum Spark Plug, part number 41-962, is engineered to rigorous standards and backed by General Motors. The center and ground electrodes both have platinum point pads, which ensure consistent voltage demands and help reduce wear on your vehicle's ignition system over time. Construction highlights include a pure copper core for a cooler electrode temperature, which maximizes durability and resistance to fouling. The one-piece suppressor seal is fired in and utilizes three glass types to create a gas-tight seal. This seal not only helps to reduce radio frequency and engine interference but also regulates spark plug energy and protects against compression pressures, contributing to a long service life. Always consult your vehicle's service manual or a trusted mechanic to confirm compatibility and recommended replacement intervals.
