Sensors Measure Exact Air/Fuel Ratio

Bosch has been a major player in the advancement of oxygen sensor technology and offers oxygen sensors for many Asian, domestic and European applications. Bosch Wideband Air/Fuel ratio sensors utilize a more sophisticated sensing element that enables them to measure exhaust gas oxygen accurately from as rich as 9.0:1 to as lean as free air. Each sensor is 100% exhaust tested for reliability and features a double laser-welded stainless steel body to protect against contamination and ensure long life. Bosch oxygen sensors are on every car running in the NASCAR Sprint Cup Series for 2014.
