Description
xOverview
Upgrade your vehicle with the BELKEBIR 2Pcs Oxygen Sensor set, designed to replace the upstream and downstream O2 sensors for select 1.4L Chevy and Buick models. This kit uses OE style part numbers for easy replacement, delivering dependable monitoring of exhaust gases to help your engine run efficiently and cleanly on the road.
The kit features two sensors, the upstream unit marked 234-4529 (and variants) and the downstream unit 234-4528 (and variants). It is intended for use on 2011 2015 Chevy Cruze 1.4L Eco LT and LTZ, 2012 2020 Chevy Sonic 1.4L L4, 2013 2020 Chevy Trax 1.4L L4, and 2013 2021 Buick Encore 1.4L L4. Important compatibility notes apply to engine variant types within the 1.4L family; the 1364cc MFI variant is compatible, while some 1399cc DI configurations used in certain 2021 models may require a different solution.
