This listing is for 2 vintage Champion spark plugs, stock number 25, model RV17YC, with the original individual retail boxes pictured. These are older replacement ignition parts suitable for a collector, restoration inventory, small-engine shop, or buyer who has independently confirmed an application. The plugs appear unused based on the clean visible electrodes and threads, but they are sold as preowned old stock because their age, storage conditions, and service history are unknown. The packaging has normal shelf wear, staining, scuffs, writing, and age-related deterioration. No resistance, gap, heat-range performance, or operational testing was performed. Compatibility varies by engine, year, equipment model, and required gap. Do not purchase based only on visual similarity. Verify Champion stock number, plug code, dimensions, reach, thread, seat type, heat range, and current cross-reference before installation. You will receive the exact quantity and boxes shown.
