Fram AR2593 Autolite Race Series Spark Plug

The Autolite AR2593 Race Series spark plug is engineered with advanced racing technology to deliver maximum performance and reliability in high-performance engines. This premium spark plug features a multi-rib insulator design that enhances electrical insulation and prevents flashover under extreme conditions.

Key Features:

• Copper core center electrode for improved heat dissipation and faster throttle response
• Large cut-back ground electrode with nickel plating for enhanced durability and heat resistance
• Extended insulator nose design resists carbon fouling in demanding race conditions
• Double terminated suppressor provides superior EMI (electromagnetic interference) suppression
• Multi-rib insulator prevents voltage loss and ensures consistent spark delivery

Designed specifically for racing applications, the AR2593 maintains optimal performance under high compression, elevated temperatures, and aggressive timing conditions. The copper core construction maximizes thermal conductivity to prevent pre-ignition and detonation.

Note: Spark plugs are priced individually but typically sold in sets of 4, 6, or 8 depending on engine configuration.
