Downstream Oxygen O2 Sensor For Ford Focus Fusion Escape – 2012-2018

Got a check engine light related to your O2 sensor?

Here’s a direct replacement downstream sensor for a bunch of Ford models.

Works on the Focus from 2012 to 2018, Fusion from 2013 to 2016, and Escape around those years too.

It’s a heated 4-wire sensor with a 26.97-inch harness and a thread diameter of 0.708 inches.

Brand is Gearzaar, part number OS01318, and it comes with a 5-year warranty—so they clearly stand behind it.

It’s a direct fit, meaning you don’t have to mess with wiring or adapters.

Just unplug the old one, screw this in, and you’re done.

Helps with fuel economy and emissions.

If your Ford’s been running rough or throwing codes, this might be the quick fix.

Easy install, solid part, and way cheaper than a dealership.
