Bosch Switching-Type Oxygen (O2) sensors provide precise air-fuel-ratio measurements to the ECU, ensuring stable combustion control and helping reduce emissions across a wide range of operating conditions. Evolving from the original thimble sensor Bosch pioneered in 1976, Bosch later developed planar narrowband designs that offer faster light-off, improved lambda accuracy, and quicker closed-loop operation. Using advanced ceramic elements, optimized heater control, and high-temperature-resistant materials, Bosch Oxygen (O2) sensors deliver consistent performance even under harsh thermal and vibration loads. Backed by more than five decades of OE development, Bosch supplies a full line of durable, accurate Oxygen (O2) sensors to the aftermarket with the same OE-proven quality trusted by vehicle manufacturers.


  • Premium Bosch oxygen sensors are designed to improve fuel economy while reducing harmful emissions
  • Direct Fit includes OE Connector for easy installation
  • Performance meets or exceeds OE specifications
  • Bosch Switching-Type Oxygen (O2) sensors reach operating temperature in under 10 seconds and delivers fast signal availability to the ECU, enabling quick closed-loop control for improved cold-start performance and lower emissions
  • Recommend to use OTC 6500 Flexihead O2 Sensor Wrench
  • [EASY INSTALL] – Engineered for quick installation with direct-fit connectors and pre-applied conductive anti-seize on threads to ensure hassle-free replacement
  • [BEST-IN-CLASS WARRANTY] – Bosch backs every Oxygen (O2) sensor with a 1-year, unlimited-mileage warranty for non-commercial passenger cars and light trucks, reflecting the quality and durability built into every unit
  • [MADE IN USA] – Bosch proudly manufactures over 90% of Oxygen (O2) sensors for the North American market out of Anderson, SC — ensuring high quality and supply reliability
  • Enhanced Engine Performance: An OE identical sensor helps maintain the correct air-fuel ratio, leading to improved engine performance, responsiveness, and overall drivability.
  • Extended Catalyst Life: By contributing to proper combustion, these sensors help protect the catalytic converter from damage and extend its lifespan.
  • Maintains Original Equipment Quality: Since OE identical sensors replicate the specifications of the original, they maintain the same level of quality and performance as the sensor installed during the vehicle's manufacturing.
  • Saves Time and Effort: The identical fit and plug-and-play installation make replacing the oxygen sensor a quick and straightforward process, saving time and effort during maintenance or repairs.
