Sensors

Quantum Fuel Systems offers a wide selection of O2 sensors, fuel pressure sensors, air-fuel ratio sensors, and flex fuel sensors to keep your vehicle running smoothly. O2 sensors are crucial in regulating the air-fuel ratio, optimizing engine performance and fuel efficiency. In powersports vehicles like motorcycles, ATVs, and snowmobiles, O2 sensors measure oxygen levels in exhaust gases and help the ECU adjust fuel injection. Regularly check your sensors, especially in harsh conditions, as failing sensors can cause reduced fuel efficiency, engine misfires, and rough idling. Replacing a faulty sensor improves fuel efficiency, performance, and lowers emissions. For high-performance applications, a wideband O2 sensor offers enhanced fuel management.
