MX-5 SENSOR,OXYGEN rear , MK4 from 2018

Lambda Sensor (rear) for Mazda MX-5 MK4 , Genuine Mazda spare part

The rear lambda sensor, also known as the O2 sensor, is an essential part of the exhaust system in your Mazda MX-5 MK4. It monitors the residual oxygen in the exhaust gases behind the catalytic converter and sends important data to the engine control unit. This ensures optimal engine performance and keeps the catalytic converter working efficiently.

If the rear lambda sensor is faulty, it may cause increased fuel consumption, poor engine performance, or an illuminated check engine light. Replacing the sensor in time helps maintain clean exhaust emissions, stable performance, and extends the lifespan of the catalytic converter.

This part is suitable for the Mazda MX-5 MK4 from model year 2018 onwards and is fitted in the rear position, after the catalytic converter. If you are looking for a reliable replacement in OEM quality, this lambda sensor is the right choice.

Suitable for:
MK4 models from 2018 onwards – chassis number from JMZND......400001
