Oxygen Sensor For Ford Focus 1.0L EcoBoost Heated Piezoelectric Air-Fuel Ratio Lambda F1FZ-9G444-A
Upgrade your Ford Focus with the F1FZ-9G444-A Oxygen Sensor (Air-Fuel Ratio Lambda). This heated, piezoelectric O2 sensor is designed for Ford Focus models from 2015 to 2018 and is compatible with 1.0L EcoBoost variants and 6F15 transmissions. By continuously monitoring exhaust gas oxygen and refining the air-fuel mixture, it helps your engine run efficiently, reduces tailpipe emissions, and protects the catalytic converter from unburned fuel. Fast warm-up and reliable signals mean smoother idle, better response, and consistent performance even in cold starts. Replacing a worn or faulty sensor restores accurate fuel delivery, supports stable idle, and helps the vehicle pass emissions tests.
All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
