Masuma Oxygen (O2) Sensor ensures stable engine operation, allowing the control unit to monitor the exhaust performance and optimize the composition of the fuel-air mixture.
Correct operation of the oxygen sensor reduces fuel consumption and exhaust toxicity, increases power and prolongs the service life of the catalytic converter.
The specifications of the Masuma oxygen sensors fully correspond to the OEM oxygen sensors. The sensors have an integrated heating element with a ceramic tip, which allows you to quickly get into operation after starting the engine. Masuma sensors have vibration protection and a dual external screen for longer service life.
Masuma produces two types of oxygen sensors: zirconium oxide (narrowband) and broadband sensors of the air-fuel ratio (A/F sensors). All sensors have factory connectors and are fully ready for installation on the car.
Service life is 30,000 km.
