Bosch 13707 Oxygen Sensor - Downstream

Bosch Validated Oxygen Sensor for Civic

Bosch 13707 is a specific-fit, narrow-band heated oxygen sensor built for precise air-fuel ratio feedback to the ECU. It is listed for 2001-2005 Honda Civic downstream applications, located after the primary converter, and uses a 4-wire harness with a threaded 18 mm mount.

For Honda Civic owners searching for a downstream O2 sensor replacement, Bosch 13707 provides OE-style signal control, fast heater response, and durable construction for stable closed-loop operation.

Key Features

• Specific-fit Bosch Validated Oxygen Sensor for direct application matching
• Fits 2001-2005 Honda Civic, downstream, located after primary converter
• Narrow-band heated oxygen sensor with 4-wire configuration
• Threaded 18 mm mounting with 22 mm hex size
• Metal housing with rectangle female connector and included wiring harness
• Standard replacement grade for emission control service
• Part number 13707 for catalog and cross-reference lookup

Product Details

Bosch developed its oxygen sensor technology through decades of OE engineering, starting with early sensor designs and later advancing to planar narrowband construction for quicker light-off and more accurate lambda control. Bosch 13707 follows that OE-focused approach with a heated narrow-band sensing element, optimized heater control, and high-temperature materials that help maintain consistent output under thermal and vibration stress. This makes it a practical replacement for downstream monitoring on the Honda Civic, where accurate exhaust feedback supports stable combustion control and emissions management. If you are replacing a worn Civic downstream O2 sensor, Bosch 13707 is a direct-fit option built around the original application requirements.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Check engine light related to downstream oxygen sensor performance
• Slow or unstable oxygen sensor response after the catalytic converter
• Incorrect air-fuel ratio feedback to the ECU
• Emissions test failures tied to sensor degradation
• Rough combustion control caused by aging narrow-band sensor output

Installation Notes and Tips

Confirm the downstream location before replacement and match the connector shape, wire count, and threaded mount to the original sensor. Bosch 13707 uses a 4-wire harness, blade terminals, a rectangle female connector, and an 18 mm thread size. The sensor is specific fit for 2001-2005 Honda Civic applications listed in the fitment data, and the notes indicate placement after the primary converter. Use the correct oxygen sensor socket for the 22 mm hex and verify the harness routing before final installation.

Quality Assurance

Bosch backs this oxygen sensor line with more than five decades of OE development and aftermarket supply experience. Bosch 13707 is built to OE-proven standards for accurate signal delivery, heater performance, and durability in demanding exhaust conditions.
