Bosch 13-62-8-515-640 Premium Wideband Air Fuel Ratio Oxygen Sensor

The Bosch 13-62-8-515-640 is a premium wideband air/fuel ratio oxygen sensor engineered to deliver precise exhaust gas monitoring for optimal engine performance and emissions control. As the world's leading oxygen sensor manufacturer and original equipment supplier, Bosch designed this sensor to meet or exceed OEM specifications for BMW diesel applications.

Advanced Wideband Technology:

Unlike conventional oxygen sensors that simply switch between rich and lean signals, this wideband air/fuel ratio sensor utilizes a sophisticated sensing element to precisely measure the exact amount of oxygen in the exhaust gases. This proportional signal allows the engine control unit to make more accurate fuel delivery adjustments, resulting in improved fuel economy, reduced emissions, and enhanced engine performance.

Key Features:

• 5-wire heated design with 40-inch wire length for flexible installation
• 18mm thread diameter with pre-coated anti-seize compound for easy installation
• True direct-fit OE connector and harness for plug-and-play replacement
• Rapid heating element reaches operating temperature (1,400°F) within 20 seconds
• Response time of less than 100 milliseconds for real-time monitoring
• Robust sensor design with seared protection tube for increased longevity
• 100% functional quality tested before packaging
• Precision-engineered ceramic sensing element for accurate readings

OEM Cross-Reference:

This sensor replaces BMW part number 13-62-8-515-640 (13628515640) and is commonly used in downstream positions. The sensor is designed for direct replacement in BMW X3 and 328d models equipped with 2.0L diesel engines.

Bosch oxygen sensors are trusted by automakers worldwide for their reliability, accuracy, and durability. When continuous exposure to extreme exhaust temperatures causes your original sensor to degrade and trigger check engine lights, this premium Bosch replacement restores proper air/fuel mixture monitoring and returns your vehicle to optimal operating condition.
