Description:
The Autolite AP23 Platinum Spark Plug is engineered to deliver reliable ignition performance, smoother engine starts, and improved acceleration. Featuring a platinum center electrode firing tip, this spark plug helps prevent gap erosion and maintains consistent spark delivery for longer service life compared to conventional spark plugs.
The copper core center electrode improves heat transfer, helping maintain optimal operating temperatures and reducing the risk of fouling. A high alumina ceramic insulator provides excellent electrical insulation and thermal conductivity, ensuring stable ignition performance. The multi-rib insulator helps prevent flash-over, while the nickel-plated shell resists corrosion and extends overall spark plug durability.
Autolite platinum spark plugs are designed to provide dependable performance in many gasoline engines and are a reliable replacement option for maintaining efficient combustion and smooth engine operation.
