Bosch Premium Wideband Air-Fuel Ratio Sensor (Dodge / Ram - Part # 17212)

Maintain precise engine tuning, optimal fuel economy, and rapid closed-loop air-fuel monitoring with Bosch Premium Wideband Air-Fuel Ratio Sensors. As the original pioneer of automotive oxygen sensors, Bosch designs wideband sensors that provide proportional signal feedback to the ECU, measuring exact oxygen concentrations across rich and lean engine conditions.

Built with sophisticated planar ceramic sensing elements and double laser-welded stainless steel housings, these sensors resist thermal shock, vibration, and exhaust contamination. Direct-fit OE connectors and pre-coated anti-seize threads ensure a hassle-free, plug-and-play installation.

Key Features & Benefits:

• Proportional Wideband Sensing: Advanced ceramic sensing element delivers real-time, precise air-fuel ratio data directly to the vehicle ECU.
• Submersible Stainless Steel Housing: Double laser-welded stainless steel construction shields internal elements against moisture and extreme exhaust heat.
• Fast-Heating Element: Integrated internal heater reaches operating temperature rapidly to enable quick closed-loop ECU operation.
• Direct OE Replacement: Precision-molded factory connectors and pre-applied anti-seize threads allow direct drop-in setup.
