Lada Kalina 1.6 oxygen sensor (OEM 0258006537, compatible with 108385001000) installed near the front of the exhaust pipe just before the catalytic converter; monitors oxygen content in exhaust and feeds ECU to adjust air-fuel ratio, ensuring combustion efficiency. Fits Lada Kalina 1.6 and 10-series models; OEM direct replacement with no modifications. Installation difficulty moderate; labor time 0.5-1 hour; when removing, avoid thread damage. If idle is unstable, fuel consumption rises, or acceleration is weak, this sensor is a key check point.
