Ensure optimal engine performance with this high-quality Lambda Oxygen Sensor, designed for installation before or after the catalytic converter. With four required per vehicle, these sensors accurately measure the oxygen levels in exhaust gases, helping maintain the ideal air-to-fuel ratio for efficient combustion.

A faulty sensor can lead to increased fuel consumption, higher CO2 emissions, and potential damage to your catalytic converter. Replacing worn sensors promptly helps protect your engine, reduce emissions, and maintain fuel efficiency.
