O2 Sensors for Automotive Exhausts
Modern day automotive engines have optimized the fuel supply to provide the best fuel efficiency, performance, and emissions. This is made possible with the help of vehicle O2 sensors. O2 sensors are designed to convert lean or rich mixtures into a voltage reading. This reading is then sent to a computer, which adjusts fuel supply to the engine so that the optimum air/fuel ratio is achieved. Car O2 sensors can also be used on carbureted engines, providing information that allows you to tune your carburetor richer or leaner to attain the best air/fuel ratio possible. JEGS offers oxygen sensors and O2 sensor fittings from top manufacturers including Denso, Caspers Electronics, AEM, NGK, JEGS, and others.
