Bosch LR140077 Oxygen Sensor Center Left O2 Sensor

The Bosch LR140077 is an OE fitment oxygen sensor designed as a direct replacement for Land Rover applications. This center left position O2 sensor monitors oxygen levels in the exhaust stream to help the engine control unit optimize air-fuel mixture for efficient combustion and reduced emissions.

Key Features:

• OEM Bosch quality oxygen sensor with part number LR140077
• Center left (driver side) mounting position
• Cross-references to OEM part numbers 16231 and LR098293
• Stainless steel body construction for durability and protection against exhaust emissions
• Heated sensor design for faster operation and optimal performance
• Factory tested to meet Bosch's rigorous quality and performance standards
• Direct-fit OE type connector for hassle-free installation

Oxygen sensors are critical emissions control components that can degrade over time due to continuous exposure to extreme exhaust temperatures. A failing O2 sensor may trigger a check engine light and cause the engine to operate inefficiently with increased emissions. Bosch leverages decades of oxygen sensor technology expertise, having invented the automotive oxygen sensor in the late 1960s, to deliver reliable performance and long service life.
