Detailed Description

Bosch 13715 is a downstream oxygen sensor for the Acura RDX that measures exhaust oxygen content and sends accurate feedback to the engine control unit. This helps maintain proper closed-loop fuel control, support stable idle and cruise operation, and keep emissions systems functioning as intended. The sensor uses a narrow-band heated design with a 4-wire layout, 16.9 in wiring harness length, and threaded installation for direct replacement service.

This Bosch oxygen sensor is part of the Bosch Validated Oxygen Sensor line, which draws on Bosch’s long OE development history in oxygen sensing technology. For shoppers searching for a Bosch 13715 oxygen sensor for 2007-2012 Acura RDX downstream replacement, this part provides the correct fitment and sensor configuration for the listed application. This part cross-references 36532RWCA01 for the same application.

What It Helps Address

• Check engine light related to downstream oxygen sensor faults
• Incorrect air-fuel ratio feedback to the ECU
• Rough idle or inconsistent fuel control caused by a failing O2 sensor
• Emissions test failures tied to sensor performance
• Slow sensor response from an aging narrow-band oxygen sensor

Installation Notes and Tips

Install Bosch 13715 in the downstream location specified for the 2007-2012 Acura RDX. Verify the 18 mm thread size, 22 mm hex size, and 4-wire connector match the original sensor before installation. Use proper exhaust sensor service practices on a cool exhaust system and route the harness away from heat and moving components.

Quality Assurance

Bosch backs this oxygen sensor with OE-focused engineering and validated aftermarket application coverage. The design uses high-temperature-resistant materials, optimized heater control, and durable construction intended to maintain accurate sensor output in demanding exhaust conditions.
