Browse spark-plug and ignition-coil guides by vehicle and engine. Start with the diagnostic section when the complaint is a rough idle, hesitation or a misfire code.
Choose the right guide
Choose the specified plug and coil for the exact application. A misfire code is a starting point for diagnosis; it does not identify a failed plug or coil by itself.
Check model year, engine and equipment on the individual page. Fitment can change within a year range. For a warning light, save the diagnostic codes and freeze-frame data first.
