Important Info
Always include your engine serial number when ordering. The application chart is a general guide, but the serial number is the only way to be 100% sure the correct part is ordered. It's also a good idea to include the OEM part number from your old part.
Ignition/electrical parts cannot be returned or exchanged, so it's important to be sure you're ordering the correct part.
