ACDelco 41-965 Professional Platinum Spark Plug, Pack of 1

The ACDelco 41-965 Professional Platinum Spark Plug is designed for improved resistance to spark erosion and corrosive combustion chamber environments. It features a platinum center electrode and a platinum pad that lower the ignition demand voltage. The one-piece integral suppressor seal helps reduce radio frequency interference, meters spark plug energy to provide long electrode life, and seals against compression leakage. This spark plug is designed with a corrosion-resistant shell and maintains a virtually unchanged spark gap during its life. Ideal for vehicles requiring platinum performance or older vehicles calling for conventional plugs, it can provide up to 100,000 miles of service in some applications.
