Autolite Platinum Spark Plug – AP5144
Description

Description:
The Autolite AP5144 Platinum Spark Plug is designed to provide dependable ignition performance, smoother engine starts, and improved fuel efficiency. Its platinum center electrode firing tip helps resist gap erosion and maintains consistent spark delivery for longer service life compared to traditional spark plugs.

The copper core center electrode enhances heat transfer, helping maintain proper operating temperatures and reducing the likelihood of fouling. A high alumina ceramic insulator delivers excellent electrical insulation and heat dissipation, ensuring stable combustion and reliable engine performance. The multi-rib insulator helps prevent flash-over, while the nickel-plated shell provides corrosion resistance for extended durability.

Autolite platinum spark plugs are engineered to meet performance expectations across many gasoline engines and are a reliable replacement option for maintaining efficient ignition performance.
