Get your 2013-2015 Ford Explorer with the 3.5L non-turbo engine running efficiently again with this complete 4-piece oxygen sensor set from PIONEER.

This kit includes both upstream (air/fuel ratio) and downstream sensors, so you have everything you need for a full replacement.

They're a direct fit, meaning they plug right into your Explorer's wiring harness and screw in without any modifications.

This set replaces a bunch of OEM numbers like 234-4489, 234-5038, and BE5Z9G444D.

Replacing worn O2 sensors can help restore fuel economy, improve performance, and keep your check engine light off.

All sensors are wired and ready to install, and they come with a 2-year manufacturer warranty.
