AULINK Oxygen Sensor Upstream & Downstream 2PCS for Hyundai Accent Veloster 2012-2014, Kia Rio/Soul 2012-2015 (1.6L L4)

Overview

The AULINK oxygen sensor set is a two-piece replacement designed for both upstream and downstream positions in select Hyundai and Kia models. Engineered to align with OEM references 234-5055 and 234-4568, this kit targets 1.6L L4 engines found in Hyundai Accent (2012–2014), Veloster (2012–2014), Kia Rio (2012–2014), and Soul (2012–2015). It’s built to fit the needs of everyday driving, offering a practical option for upkeep and restoration of sensor performance.

Durable construction for real-world use

The sensors feature a double laser-welded stainless steel body that is fully submersible, delivering a robust seal against moisture and contaminants. The rugged stainless housing resists corrosion in the engine bay, supporting a longer service life and stable sensor readings across varied driving conditions. This level of durability can be especially valuable for drivers who log frequent short trips, temperature swings, or exposure to road spray.

Design that supports reliable sensing

Key design choices help keep the sensing element accurate by controlling how air enters the chamber. The entry design allows atmospheric oxygen to reach the sensing area while limiting water and other substances from seeping into the casing, which can help reduce clogging of the internal pathways and maintain steady data to the engine control system over time.

• OEM Part Numbers include 234-5055, 234-4568, 2345055, 2344568, and related Hyundai/Kia references
• Durable stainless steel housing and a sealed design to resist corrosion and moisture
• Two-piece kit to replace both upstream and downstream sensors as a matched set

• Compatibility covers Hyundai Accent (2012–2014), Veloster (2012–2014), Kia Rio (2012–2014), Soul (2012–2015) with 1.6L L4 engines
• Includes a 1-year or 50,000 km warranty for peace of mind

Note: While these features describe the product design and build, actual performance can vary based on vehicle condition and driving patterns. The aim is to provide a reliable component that supports consistent oxygen data and vehicle control under typical driving conditions.

What you get and fitment tips

This two-piece sensor set is intended to replace both upstream and downstream sensors on the listed models, aligning with the 1.6L L4 configuration. If you are replacing only one sensor, verify your vehicle’s current sensor position and refer to the OEM part references to ensure a proper match for your specific trim and year.
