This part fits a wide range of Buick, Cadillac, Chevrolet, and Daewoo models. You must verify your specific model and engine type against the 48407 cross-reference list before purchasing.
Yes, the 48407 coil is supplied as a complete assembly, including the integrated boot component.
While it is often recommended to replace all ignition coils simultaneously to maintain balanced engine performance, it is not strictly required if only one has failed.
The 7-pin connector acts as the interface between your vehicle's Engine Control Unit (ECU) and the ignition coil, transmitting the signals required to fire the coil at the precise time for combustion.
Warranty terms vary by retailer. Please check the documentation provided with your specific purchase or the manufacturer website for the official warranty duration.
Check that the 7-pin connector is fully seated and clicked into place. Inspect the wiring harness for signs of fraying or heat damage.
Ensure the spark plug at the end of the coil is not fouled or worn out, as a new coil can often highlight issues with older spark plugs.
Installation of the NGK 48407 requires standard automotive tools including a socket set and potentially a torque wrench. Before beginning, ensure the ignition is switched off and the battery negative terminal is disconnected to prevent accidental shorting.
Compatibility is critical for this part; always compare the part number 48407 against your vehicle's specific engine code or consult your owner's manual. For care, keep the engine bay clean to prevent debris from settling around the electrical connections, which can lead to corrosion over time.
