Bosch 13258 Oxygen Sensor - Upstream

Bosch Oxygen Sensor for Honda Prelude

Bosch 13258 is a narrow-band heated oxygen sensor built for precise air-fuel-ratio feedback to the ECU. It is a specific-fit replacement for select 1997-2000 Honda Prelude upstream applications, including the Bosch Engineered Oxygen Sensor line.

Key Features

• Specific-fit oxygen sensor for select Honda Prelude upstream locations
• Narrow-band heated design for closed-loop fuel control
• 4-wire configuration with rectangular female connector
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Metal housing with a steel finish for underbody durability
• Wiring harness included with a 20.7 in harness length
• Bosch part number 13258 for direct catalog lookup

Product Details

Bosch 13258 uses a switching-type narrow-band sensor element to send accurate oxygen-content feedback to the engine control unit. That signal helps the ECU maintain stable combustion control across changing load and temperature conditions. Bosch’s oxygen sensor development includes early OE thimble designs and later planar narrowband technology, with a focus on faster light-off, improved lambda accuracy, and quicker closed-loop operation.

This Bosch Engineered Oxygen Sensor is listed for 1997-2000 Honda Prelude upstream positions. If you are searching for a Honda Prelude upstream oxygen sensor replacement, Bosch 13258 provides the OE-style fitment and sensor layout needed for the application. This part cross-references Honda 36531P5M014 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rich or lean fuel mixture readings at the ECU
• Slow closed-loop response after startup
• Reduced fuel control accuracy during normal driving
• Emissions test failures tied to upstream sensor faults

Installation Notes

Fits 1997-2000 Honda Prelude, upstream. Confirm the threaded mounting location, connector shape, and wire count before installation. Use the existing harness routing and verify the sensor seats correctly in the exhaust bung with the proper 18 mm thread size. Because this is a heated narrow-band sensor, proper electrical connection is important for accurate operation.

Quality Assurance

Bosch has more than five decades of OE oxygen sensor development and supplies aftermarket sensors built to OE-proven standards. Bosch 13258 is part of the Bosch Engineered Oxygen Sensor line, which reflects Bosch’s long history in oxygen sensor design and production.
