Bosch 17465 Wideband AFR Oxygen Sensor, Original Equipment

The Bosch 17465 is a premium wideband air-fuel ratio (AFR) oxygen sensor designed for precise measurement and engine management control. This wideband sensor provides continuous, high-precision measurements of the air-fuel ratio across the full lambda range, delivering superior accuracy compared to traditional switching-type oxygen sensors.

Key Features:

• Wideband AFR sensing technology for exact air-fuel mixture monitoring
• 5-wire planar design for fast response and accurate readings
• Original equipment quality from the inventor of automotive oxygen sensors
• Compatible with gasoline, diesel, E85, and alternative fuel applications
• Designed for use with wideband AFR controllers and aftermarket ECUs
• Fast light-off time and optimized heater control

This sensor enables exceptionally accurate air-fuel mixture control, supporting improved fuel efficiency, engine performance, and reduced emissions under all operating conditions. The sensor is laboratory-calibrated at the Bosch factory to be accurate to 0.1 AFR, ensuring reliable performance for both OEM applications and performance tuning. Bosch wideband sensors feature robust ceramic construction designed to withstand harsh thermal cycles and rapid load changes in demanding automotive environments.
