Installation Notes and Tips

Verify the connector style, terminal layout, and OE coil reference before installation. This coil uses a female connector, male terminals, and a blade-style terminal design, so matching the original configuration is important for proper fitment. Confirm whether your vehicle uses an Eldor, Beru, Borg-Warner, or other listed OE coil reference in the fitment notes before ordering.

For best results, inspect spark plugs and related ignition components at the same time, since worn plugs can place added stress on the coil. Clear diagnostic trouble codes after installation and confirm normal engine operation during a road test.
