OXYGEN SENSOR

Bosch Wideband A/F Oxygen (O2) sensors provide continuous, high-precision measurements of the air-fuel ratio across the full lambda range, giving the ECU far more detailed information. These sensors deliver high-resolution, real-time air-fuel data that surpasses the limited feedback of switching sensors, allowing for cleaner combustion, better fuel economy, and maximum performance. Bosch invented the Oxygen (O2) sensor and Wideband A/F technology and has supplied OE manufacturers for more than 50 years. They are built to withstand exhaust streams up to 1,880°F, feature stainless steel housings, integrated heater elements, advanced ceramic elements, and TSP coating to resist vibration, corrosion, and contamination. They include true Direct-fit OE connectors and harness and pre-applied conductive anti-seize on threads for easy installation. Bosch offers a 1-year, unlimited-mileage warranty for non-commercial passenger cars and light trucks. Over 90% of Oxygen (O2) sensors for the North American market are proudly manufactured in Anderson, SC, USA.
