Set (4pcs) Autolite Platinum Core Spark Plugs Resistor Gasket Seat 14mm x 1.25 Thread AP3923

This platinum 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 platinum core construction, a 14 millimeter by 1.25 thread size, a gasket seat design, and a resistor configuration intended to meet specific engine requirements. The set includes four spark plugs and does not include ignition wires, coils, or additional engine system components. This product does not modify engine design, output, 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. Installation should be performed according to engine or vehicle manufacturer specifications. The installer is responsible for verifying fitment, adjusting gap if required, and ensuring proper engine operation after installation.
