Bosch LR140079 Oxygen Sensor Center Right O2 Sensor

The Bosch LR140079 is a direct-fit center right oxygen sensor (O2 sensor) engineered as a genuine OEM-quality replacement. As the world's original inventor of the automotive oxygen sensor, Bosch brings decades of sensor technology and innovation to this precision component, delivering performance that meets or exceeds original equipment specifications.

This sensor monitors oxygen content in the exhaust stream and transmits real-time signals to the engine control unit (ECU), allowing the ECU to continuously optimize the air-fuel mixture for efficient combustion and reduced harmful emissions. A failed or degraded O2 sensor can trigger a check engine light and cause the engine to run on preset fault parameters, reducing fuel economy and increasing emissions output.

Key Features:

• Direct-fit OE replacement — installs without modification
• Includes OE-matched connector and wiring harness for plug-and-play installation
• Threads pre-coated with anti-seize compound for easy installation and future removal
• Fast-acting heater element brings sensor to operating temperature quickly for optimum performance
• Stainless steel body sealed against exhaust heat and moisture for extended service life
• Performance meets or exceeds OEM specifications
• Excludes SULEV (Super Ultra Low Emission Vehicle) applications

Bosch oxygen sensors are 100% tested for full functionality before leaving the factory, ensuring every sensor meets Bosch's rigorous quality and performance standards. Replacing a worn O2 sensor at recommended intervals helps prevent engine damage, restore fuel economy, and keep emissions in compliance.
