Wideband Oxygen Sensors
Wideband Oxygen Sensors

Detect the exact amount of unburned fuel in the exhaust stream
Sensor communicates with the onboard computer allowing the optimal amount of fuel to be injected into the engine, leading to better fuel economy and lower emissions
“True Direct Fit” Sensors
- Bosch utilizes OE connectors, and all Bosch-made oxygen sensors also feature an OE-style harness. That means a continuous wire from connector to sensor
- No crimping
100% Exhaust testing
Every sensor is tested in simulated exhaust gas to ensure the highest quality
Manufactured on OE production line
Bosch wideband A/F oxygen sensors for the aftermarket are produced on the same production line as our OE sensors
Double laser-welded stainless steel body
- Fully submersible in water
- Air-tight seal protects against contamination to ensure long life.
