Kia Optima Oxygen O2 Sensor

Re-conditioned Oxygen O₂ Sensors for Kia Optima / K5 – Imported from Korea

For Kia Optima (also known as Kia K5) owners in Sri Lanka, a properly functioning oxygen (O₂) sensor is essential for maintaining fuel efficiency, smooth performance, and lower emissions. Also called a lambda sensor, this component monitors oxygen levels in the exhaust system and transmits data to the Engine Control Unit (ECU). The ECU then adjusts the air-fuel ratio for optimal combustion, helping your car deliver better mileage, reduced emissions, and consistent engine power.

Over time, oxygen sensors can become less effective due to carbon deposits, high exhaust heat, and impurities in fuel. A failing sensor may send inaccurate readings to the ECU, causing the engine to run too rich or lean. This results in higher fuel consumption, unstable idling, loss of power, and increased exhaust smoke.

We supply high-quality re-conditioned oxygen sensors imported directly from Korea for Kia Optima / K5 models in Sri Lanka. Each sensor is fully restored through deep cleaning, recalibration, and testing to ensure reliable long-term performance comparable to factory standards.
