Fram AR93 Autolite Racing Spark Plug Non-Resistor 14mm Tapered Seat

The Fram AR93 (Autolite AR93) is a high-performance racing spark plug designed for extreme conditions and demanding motorsports applications. Used by many professional race car drivers, these spark plugs contain an Yttrium-Enhanced Alloy which enables up to 8 percent reduction in side wire temperature for improved durability and less pre-ignition.

Key Features:

• Cut back ground electrode for better heat transfer
• Cut-back ground electrode exposes spark for quicker acceleration with nickel plated shell to prevent corrosion
• 14mm thread size with 0.708 inch reach and tapered seat
• Non-resistor design with chromium nickel alloy electrode tip
• Medium heat range suitable for racing applications
• Power Tip design with 5/8 inch hex

This copper core racing spark plug is engineered for modified engines operating under intense conditions. Available in colder heat ranges than most plug manufacturers to support modified engines. The non-resistor design makes this plug ideal for race-only applications where maximum performance is required.
