Description
xEnhance engine sensing with ATBIZZLE O2 sensors
The ATBIZZLE Air Fuel Ratio Sensor and Oxygen Sensor kit delivers upstream and downstream sensing solutions designed for select Kia and Hyundai 1.6L engines from 2012 to 2017. Built to withstand real-world conditions, the sensors combine a ceramic core with precious metal-coated electrodes to provide quick, reliable readings that help your vehicle’s engine control system fine-tune the air-fuel balance.
Crafted for durability, the sensor housing uses high-temperature-resistant 310S stainless steel, offering strong corrosion resistance and long-term reliability under varying driving temperatures. A pre-applied anti-seize coating on the threads simplifies installation and reduces the chance of thread galling during service or replacement.
What you get and how it fits
This kit includes both upstream and downstream sensors, compatible with a range of Hyundai and Kia 1.6L models (e.g., Kia Rio, Kia Soul, Hyundai Accent, Veloster). The part numbers 234-5055 and 234-4568 align with common replacements, helping you easily pair the right sensors with your vehicle. Before purchase, please verify wire length, connector type, and compatibility by year, brand, model, engine, and installation position.

Real-life scenarios and practical benefits
In daily driving, these sensors may help your engine control unit optimize the air-fuel mix as you accelerate, cruise, or idle. Replacing aging sensors can restore the system’s ability to monitor exhaust composition, potentially supporting smoother starts and more stable performance across different loads. While results vary by vehicle and driving style, a fresh sensor pair can contribute to responsive throttle behavior and a steadier overall drive.
- May contribute to more accurate fuel-air calibration across varied conditions.
- Could support efficient combustion and reliable exhaust monitoring with durable materials.
Important note: before buying, verify wire length, connector type, and compatibility (year, brand, model, engine, and installation position). The kit includes an 18-month unlimited mileage guarantee and our team is happy to help verify compatibility if needed.
