Set (8pcs) Autolite Copper Core Spark Plugs Resistor Tapered Seat 18mm x 1.50 Thread 5125

This copper core spark plug set is designed as a replacement ignition component for use in compatible automotive engines equipped with spark plug-based ignition systems. Each spark plug features a copper core construction, an 18 millimeter by 1.50 thread size, a tapered seat design, and a resistor configuration intended to meet specific engine ignition requirements. The set includes eight spark plugs and does not include ignition wires, coils, or additional engine system components. This product does not modify engine design, output, fuel usage, or operating characteristics beyond restoring intended ignition function when properly installed. Correct performance depends on accurate engine compatibility, proper spark plug gap, correct torque during installation, and overall engine condition.
