Additionally, verify that your current coil matches one of the listed OEM part numbers: 581407, 502880, 0502880, 0581407, or aftermarket 18-5196.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What are the signs that my ignition coil needs replacement?\u003c\/strong\u003e\u003cbr\u003e\nA: Common symptoms include difficulty starting the engine, misfiring, rough idling, loss of power, or complete loss of spark. If your engine cranks but won't start, testing the coil's output with a spark tester can help diagnose the issue.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: How often should I replace the ignition coil?\u003c\/strong\u003e\u003cbr\u003e\nA: Ignition coils typically last many years under normal conditions, but exposure to moisture, vibration, and heat can accelerate wear. Replace the coil if you experience ignition problems or during routine maintenance if the coil shows signs of corrosion, cracks, or electrical failure.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Will the color of the coil affect performance?\u003c\/strong\u003e\u003cbr\u003e\nA: No, the color of the ignition coil casing is cosmetic and does not impact electrical performance or fitment.
