Does this replace the whole oxygen sensor?

No. It is only the connector pigtail that joins the sensor to the wiring harness. A failed sensor still needs a new sensor.

Fit depends on the vehicle and the connector style on your harness. Match the S938 to your model's application before buying.

Can I splice it into my existing wiring?

It is a pigtail, so it is made to be spliced into the harness in place of the damaged plug. Follow the wiring instructions for your vehicle.

It is an aftermarket part built to OEM specifications, not a factory-branded part.

The connector pigtail itself. Check whether your repair needs extra wire, heat shrink or terminals.
