Autolite Double Platinum Spark Plug – APP3923
Description

Description:
The Autolite APP3923 Double Platinum Spark Plug is engineered to deliver reliable ignition performance, reduced misfires, and extended service life. Its platinum-to-platinum firing design places platinum pads on both the center and ground electrodes, helping reduce gap erosion and maintain consistent spark delivery over time.

A copper core center electrode enhances heat transfer, helping maintain proper operating temperatures and reduce fouling. The yttrium-enhanced ground electrode improves durability under high temperatures and pressure, making it well-suited for distributorless ignition system (DIS) engines. The high alumina ceramic insulator provides excellent dielectric strength and thermal conductivity, while the multi-rib insulator helps prevent flash-over for dependable ignition performance.

Autolite double platinum spark plugs are designed to deliver long-lasting reliability and consistent ignition performance for many gasoline engine applications.

Features:

  • Platinum-to-platinum firing design reduces gap erosion and extends spark plug life

  • Copper core center electrode improves heat transfer and fouling resistance

  • Yttrium-enhanced ground electrode increases durability under high heat and pressure

  • High alumina ceramic insulator improves thermal conductivity and insulation

  • Multi-rib insulator helps prevent flash-over for reliable ignition performance
