Oxygen Sensor Set for Hyundai Elantra Upstream and Downstream 234-5083 234-4552

This Hyundai Elantra Oxygen Sensor Upstream and Downstream set delivers two OEM-style sensors (part numbers 234-5083 and 234-4552) designed to restore precise air-fuel readings for Hyundai and Kia vehicles. By replacing both the upstream and downstream O2 sensors, you’ll reestablish proper fueling, smoother idling, and cleaner exhaust emissions—helping your engine run efficiently again rather than running rich or lean due to worn sensors.

Compatible across a broad range of models and years, this 2-sensor kit targets the critical oxygen-sensing points in your exhaust system. It’s built to match the performance of the original equipment so your engine control unit (ECU) receives accurate data for optimal ignition timing, fuel delivery, and emissions control. With this kit, you don’t just replace worn parts—you reintroduce reliable monitoring that supports better fuel economy and reduced exhaust emissions over time.

All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty. At intercyprus.com since 2002 — trusted for quality and reliability.

Benefits & Tips

• Restore accurate oxygen readings for both upstream and downstream sensors to improve driveability, fuel economy, and emissions compliance.

• When in doubt about fit, verify the part numbers 234-5083 or 234-4552 with your original components before installation to ensure OE-style fitment.
