Bosch 17025 Premium Wideband A/F Oxygen (O2) Sensors are designed for use with aftermarket high performance wideband kits. Wideband/air-fuel sensors perform the same function as a regular O2 sensor, but they precisely measure the amount oxygen in the exhaust rather than just switching between rich (too much fuel, not enough oxygen) and lean (too much oxygen, not enough fuel). Our wideband sensors use a more sophisticated sensing element that provides a signal that is proportional to the amount of oxygen in the exhaust. Engineered and manufactured with a robust sensor design that increases sensor longevity. 'True Direct-fit' OE connectors and harness, plus threads pre-coated with anti-seize compound right out of the box, make installation easy. Seared protection tube due to 100% functional quality test.
