Bosch C2D39892 Heated Oxygen Sensor

The Bosch C2D39892 is a premium heated oxygen sensor designed to deliver precise air-fuel ratio monitoring for optimal engine performance and emissions control. This OE-specification sensor features advanced zirconia ceramic element technology and integrated heater circuitry for rapid light-off and accurate lambda readings across all operating conditions.

Key Features:

• Heated sensor design ensures fast response time and reliable operation in all temperatures
• Advanced ceramic element construction provides accurate oxygen content measurements
• Corrosion-resistant stainless steel body sealed against exhaust emissions for extended service life
• 4-wire configuration with vehicle-specific connector for direct OE replacement
• Meets or exceeds original equipment specifications for fit, form, and function
• Manufactured by Bosch, the original inventor of automotive oxygen sensors since 1976

Oxygen sensors are critical emission control components that monitor exhaust gases and send feedback to the engine control unit (ECU) to maintain the ideal 14.7:1 air-fuel ratio. A failing oxygen sensor can trigger check engine lights, reduce fuel efficiency, decrease performance, and increase harmful emissions. This Bosch sensor ensures your engine operates at peak efficiency while minimizing environmental impact.
