4PCs Front & Rear Oxygen Sensor Set For 2014-2015 Ford Explorer 3.5L Non-Turbo – Direct Fit O2 Sensors

Got a 2014 or 2015 Ford Explorer with the 3.5L non-turbo engine?

If your check engine light is on or your fuel economy's gone wonky, might be time for new O2 sensors.

This set includes all four—front and rear—so you can replace the whole lot at once and be done with it.

They're 4-wire sensors, direct fit, meaning they plug right in with no splicing or drama.

Interchange numbers include 9E5Z9F472D, BL3Z9F472A, OS5578, DY1178, and a bunch more—so cross-reference if you want, but these are the ones.

Manufacturer part numbers 234-5038 and 234-4490.

Unbranded, but they come with a 6-month warranty.

Made to OEM specs, so they should get your Explorer running right again.

Easy installation, just unplug the old ones and bolt these in.

Get your engine breathing properly and save at the pump.
