Bosch 18207 Premium Wideband A/F Oxygen Sensor

The Bosch 18207 Premium Wideband A/F Oxygen Sensor precisely measures the amount of oxygen in the exhaust rather than just switching between rich and lean conditions. This wideband sensor uses a more sophisticated sensing element that provides a signal to the vehicle's ECU that is proportional to the amount of oxygen in the exhaust, enabling exceptionally accurate air-fuel mixture control for improved fuel efficiency, engine performance, and reduced emissions.

Key Features:

• Provides continuous, high-precision measurements of the air-fuel ratio across the full lambda range
• Fast light-off and optimized heater control for reliable performance during rapid load changes and harsh thermal cycles
• Uses planar pump-cell design to measure air-fuel ratio continuously by regulating internal pump-cell current to maintain precise oxygen balance
• Robust ceramic construction for durability in demanding exhaust environments
• Backed by more than five decades of OE development with OE-proven quality

Bosch pioneered the first Wideband A/F Oxygen Sensor, introducing the planar pump-cell design that has become the global standard for modern engine management and low-emission technologies. This sensor enables exceptionally accurate air-fuel mixture control, supporting improved fuel efficiency, engine performance, and reduced emissions under all operating conditions.
