ATBIZZLE O2 Oxygen Sensor 2-Pack — Upstream & Downstream Direct-Fit for 2012–2017 Hyundai/Kia 1.6L

ATBIZZLE's 2-piece air fuel ratio and oxygen sensor set replaces upstream and downstream O2 sensors for select 1.6L Hyundai and Kia models, restoring accurate air/fuel readings and emissions monitoring.

This pair of sensors is engineered as a direct-fit aftermarket replacement for the upstream (air–fuel ratio) and downstream (oxygen) positions on many 1.6L naturally aspirated Hyundai and Kia vehicles from model years 2012–2017. Each sensor uses high-quality ceramic elements and precious-metal coated electrodes inside a 310S stainless-steel housing for corrosion resistance and rapid response. The kit arrives ready-to-install with anti-seize pre-applied to the threads and includes the common OEM cross-reference numbers so you can confirm fitment before purchase.

Which vehicles and positions are these sensors designed to fit?

The ATBIZZLE set fits upstream (air–fuel ratio) and downstream (oxygen) sensor locations for specific Hyundai and Kia 1.6L models. Always verify the year, engine, and installation position against your original sensor to ensure compatibility.

• Hyundai Accent (2012–2017) L4 1.6L — upstream and downstream positions supported
• Hyundai Veloster (2012–2015, 2013–2015 listed years) L4 1.6L — compatible for naturally aspirated engines
• Kia Rio (2012–2016) and Kia Soul (2012–2016) L4 1.6L — both upstream and downstream fitment
• Cross-reference: replaces 234-5055, 234-4568 and multiple OEM numbers listed for easy matching

How do these sensors perform compared with OEM parts?

ATBIZZLE sensors are built with durable materials and fast-reacting electrodes to provide stable voltage signals and accurate oxygen concentration measurement. They are designed to meet the physical fit and electrical characteristics expected in upstream and downstream positions without costly modifications.

• Ceramic sensing element and precious-metal coating for reliable signal generation
• 310S stainless-steel housing resists heat and corrosion in exhaust environments
• Pre-applied anti-seize on threads for easier removal and installation
• Engineered to match OEM connector and wiring lengths for direct replacement when matched

What should I check before ordering to avoid fitment issues?

Because O2 sensors vary by wire length, connector type and installation location, compare your original sensor to the replacement details. Confirm year, model, engine code and whether the sensor is upstream or downstream to prevent returns.

• Compare connector shape and pin count with your existing sensor plug
• Measure wire length from harness to sensor body to ensure reach
• Confirm the sensor’s OEM cross-reference numbers against your part number
• Check if your vehicle is naturally aspirated 1.6L — turbocharged variants differ

What warranty and support come with this ATBIZZLE sensor set?

Each purchase is backed by an 18-month unlimited-mileage guarantee supported directly by the seller. If you need help confirming compatibility or experience issues after installation, contact customer service for guidance or replacement options.

• 18-month unlimited mileage guarantee from ATBIZZLE
• Seller support for compatibility checks before installation
• Clear list of replaced OEM and aftermarket reference numbers included

Who is this for: This 2-piece ATBIZZLE sensor set is intended for DIY mechanics and professional technicians who need a reliable, cost-effective replacement for upstream and downstream O2 sensors on compatible 1.6L Hyundai and Kia models. It is also suitable for vehicle owners troubleshooting check-engine codes related to oxygen sensor circuits, provided they confirm connector type and wire length before ordering.
