QIYBONE Oxygen Sensor Kit Upstream & Downstream 2PC for Hyundai/Kia 1.6L (2012–2018) Stainless Steel OEM Fit

If your check engine light, fuel economy, or emissions performance suggests an oxygen sensor issue, this two-piece QIYBONE kit provides both upstream and downstream O2 sensors engineered to fit Hyundai Accent and Veloster, and Kia Rio and Soul models with the 1.6L L4 engine from 2012–2018. Built to meet OEM fitment and electrical connector patterns, these sensors are intended as direct replacements for a range of factory part numbers so you can swap them in without major wiring changes.

Which vehicles and part numbers do these sensors replace?

The QIYBONE kit covers a clear list of Hyundai and Kia 1.6L vehicles and corresponds to multiple OE reference numbers so it’s easier to find a match for your car. Review the vehicle models and the part number cross-references before ordering to confirm compatibility.

• Vehicle fitment: Hyundai Accent (2012–2017), Hyundai Veloster (2012–2017), Kia Rio (2012–2018), Kia Soul NON-TURBO (2012–2018).
• Upstream references: 234-5055, 24326, 39210-2B210, 39210-2B410 and equivalents.
• Downstream references: 234-4568, 39210-2B220 and equivalents.
• Designed to replace both upstream and downstream factory sensors in one kit (2PCS).

How are these sensors constructed and how durable are they?

QIYBONE sensors use stainless-steel housings and high-temperature materials to stand up to the thermal and chemical conditions in the exhaust stream. The units are sealed and protected to reduce water or contamination ingress and extend service life compared with lower-quality aftermarket options.

• Stainless steel construction for corrosion resistance.
• High-temperature resistant internal materials for long-term stability.
• Double-seal design to minimize exhaust leaks at the sensor mounting point.
• Manufactured to withstand typical engine heat cycles and road conditions.

What performance benefits should I expect after installing them?

Replacing a failing oxygen sensor can restore accurate air-fuel mixture feedback to the engine control unit, improving fuel metering and emissions control. While these sensors don’t change engine fundamentals, a healthy upstream and downstream pair helps the engine run more efficiently and can reduce rough idling, misfires, or rich/lean diagnostic codes.

• Faster and more accurate air-fuel ratio readings returned to the ECU.
• Improved fuel efficiency when the control system regains correct feedback.
• Reduced risk of persistent OBD-II oxygen sensor or catalytic converter codes.
• Consistent response times to throttle or load changes for smoother operation.

Is installation difficult and what should I check before buying?

These sensors are built to OEM-style specifications with plug-and-play connectors for a straightforward swap in most cases. Basic hand tools and an oxygen sensor socket are usually sufficient; compare your existing sensor connectors to the product images to confirm an exact plug match before purchase.

• Designed for direct fit—match connector shape against your old sensor.
• Typical installation requires an O2 sensor socket and moderate mechanical skill.
• Allow engine and exhaust to cool before removing the old sensor for safety.
• Clear any active OBD-II codes after replacement to confirm success.

Who is this for: This QIYBONE two-piece oxygen sensor kit is targeted at owners and mechanics who need a ready-to-install upstream and downstream replacement for Hyundai Accent or Veloster and Kia Rio or Soul 1.6L models (2012–2018). It’s suitable for DIYers comfortable with basic under-vehicle work, independent shops seeking affordable OE-style parts, and drivers troubleshooting emissions or fuel-efficiency issues who want a matched sensor pair to restore factory-like performance.
