Autolite Platinum Spark Plug – AP5364
Description

Description:
The Autolite AP5364 Platinum Spark Plug is engineered to deliver dependable ignition performance, smoother starts, and improved engine efficiency. Featuring a platinum center electrode firing tip, this spark plug helps resist gap erosion and provides longer service life compared to conventional copper plugs.

Its copper core center electrode enhances heat transfer for stable operating temperatures, while the high alumina ceramic insulator offers excellent electrical insulation and durability. The multi-rib insulator design helps prevent flash-over, ensuring consistent spark delivery and reliable combustion. A corrosion-resistant nickel-plated shell protects against rust and wear, supporting long-term reliability in a wide range of gasoline engines.

Autolite platinum spark plugs are designed to provide consistent ignition performance and are a reliable upgrade or replacement for many older engine designs.

  • Platinum center electrode firing tip helps resist gap erosion for extended service life

  • Copper core center electrode improves heat transfer and ignition stability

  • Multi-rib ceramic insulator helps prevent flash-over for consistent spark delivery
