Buick Regal Ignition Coil H6T15371ZC OEM Replacement

Buick Regal original replaceable ignition coil, OEM number H6T15371ZC, designed for 4-cylinder engines. Mounted above the cylinder head and connected to the spark plug, converts 12V low voltage to high voltage to ensure proper ignition of the air-fuel mixture in the cylinder. Installation difficulty is medium; labor about 1.5 hours; pay attention to high-voltage wire order. If rough idle, weak acceleration, check engine light, or higher fuel consumption occur, ignition coil may be aging or arcing and should be replaced promptly.
