URO 11787558087 Oxygen Sensor Pre-Catalytic Converter

The URO 11787558087 is an aftermarket oxygen sensor designed as a direct replacement for BMW vehicles equipped with N54 turbocharged engines. This pre-catalytic converter oxygen sensor monitors exhaust gas composition to help the engine control module optimize the air-fuel mixture for maximum performance and efficiency.

Key Features:

• Direct replacement for BMW OEM part number 11787558087
• Front bank oxygen sensor placement (Bank 2, cylinders 4-6)
• Wideband 5-wire design for accurate air-fuel ratio sensing
• Manufactured to meet or exceed OE specifications for fit and function
• Produced in ISO 9000 certified facilities
• Compatible with 2007-2016 BMW models with N54 engines

This oxygen sensor plays a critical role in maintaining proper engine performance by continuously measuring exhaust oxygen levels and sending voltage signals to the powertrain control module. When the sensor detects a lean mixture, the PCM increases fuel delivery; when it detects a rich mixture, fuel is reduced to maintain optimal combustion efficiency and minimize emissions.

Technical Specifications:

• Sensor Type: Wideband oxygen sensor
• Wire Configuration: 5-wire
• Position: Pre-catalytic converter (upstream)
• Cross-Reference: Also known as lambda sensor or air-fuel ratio sensor

URO Parts are manufactured by A.P.A. Industries and undergo rigorous testing to ensure quality and durability. Each component is inspected against genuine OE samples to maintain consistent standards. While URO offers an economical alternative to OEM parts, proper installation and verification of fitment is essential for optimal performance.
