Product Details

Bosch developed this switching-type oxygen sensor to provide accurate exhaust oxygen feedback to the ECU, helping maintain stable combustion control and emissions performance. The narrow-band heated design supports quicker closed-loop operation and faster light-off, while the ceramic sensing element and controlled heater response help maintain consistent readings under thermal and vibration load. Bosch Part Number 13819 reflects the brand’s OE-focused oxygen sensor line, which is built around long-term durability and accurate lambda measurement.

This part cross-references 162462 and 169953 for the same application. It is a direct-fit oxygen sensor for Ferrari 456 M GT, Ferrari 456 M GTA, Ferrari 550 Maranello, Ferrari 456 M, Ferrari F355 Spider, Ferrari 456 GT, Ferrari 456 GTA, Ferrari F355 F1, Ferrari F355 GTS, and Ferrari F355 Berlinetta applications listed below.

What This Oxygen Sensor Helps Address

• Rich or lean air-fuel mixture readings at the ECU
• Delayed closed-loop fuel control after startup
• Check engine light concerns related to oxygen sensor performance
• Unstable idle or drivability issues tied to exhaust feedback
• Emissions test failures caused by inaccurate sensor output
