Spark PlugSpark plug offered as an aftermarket replacement for forklift gasoline and LPG ignition systems. The plug delivers the high-voltage arc that ignites the air-fuel mixture in the combustion chamber, with reach, heat range, and electrode geometry matched to the OE spec. It restores consistent ignition energy and stable idle when the original plug shows electrode wear, fouling, or porcelain cracking. Gap the plug to the published spec before installation, apply anti-seize sparingly on dry threads if the OE procedure calls for it, thread by hand to avoid cross-threading, and torque to spec so the gasket seals correctly without crushing the seat.Aftermarket replacement part, cross-references original part number AC24-5000.Need help confirming fit?
