Bosch 18063 Oxygen Sensor - Upstream, Upstream Left or Upstream Right

Bosch Wideband O2 Sensor for Nissan and INFINITI

Bosch Validated Oxygen Sensor 18063 is a specific-fit wideband air/fuel sensor built for precise mixture feedback to the engine control unit. It is listed for 2008 INFINITI G37 upstream and 2009-2010 Nissan Murano upstream left or upstream right, making it a direct-match option for common Nissan and INFINITI oxygen sensor replacement needs.

Key Features

• Wideband oxygen sensor design for continuous air-fuel ratio measurement across the full lambda range
• Heated sensor with optimized heater control for faster light-off
• Specific fit with square connector, male connector gender, and 4-wire configuration
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Wiring harness included with 15.8 in harness length and 15.7 in overall length
• Standard replacement grade for OE-style service applications
• Metal housing and robust ceramic construction for thermal durability

Product Details

Bosch 18063 uses wideband sensing technology to provide the ECU with more detailed air-fuel ratio data than a conventional switching sensor. That level of feedback helps maintain accurate fuel control during idle, cruise, acceleration, and rapid load changes. Bosch pioneered the first wideband A/F oxygen sensor, and this Bosch Validated Oxygen Sensor line reflects that OE development history in a service part for the 2008 INFINITI G37 and 2009-2010 Nissan Murano.

This part cross-references Nissan 22693EY00A and 22693EY00B for the same application. The Bosch Validated Oxygen Sensor brand line focuses on OE-proven sensor design, fast response, and stable operation under repeated heat cycling.

Common Issues This Sensor Can Help Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings from a worn upstream sensor
• Poor fuel economy caused by inaccurate exhaust feedback
• Rough idle or hesitation tied to delayed sensor response
• Emissions test failure from degraded sensor output

Installation Notes and Tips

Install Bosch 18063 in the upstream left or upstream right position on 2009-2010 Nissan Murano, or in the upstream position on 2008 INFINITI G37. Confirm the connector shape, 4-wire layout, and 18 mm thread size before installation. Use proper oxygen sensor service tools and follow the vehicle service procedure for routing the harness away from heat and moving components.

Quality Assurance

Bosch backs this oxygen sensor with more than five decades of OE development experience and supplies aftermarket sensors built to the same engineering standards used by vehicle manufacturers.
