Bosch 13275 Oxygen Sensor - Downstream or Upstream

Bosch Engineered Oxygen Sensor 13275

Bosch 13275 is a specific-fit, narrow-band heated oxygen sensor built for upstream and downstream applications on a wide range of Chrysler, Dodge, Jeep, and Plymouth vehicles. It delivers air-fuel-ratio feedback to the ECU for stable closed-loop fuel control and emissions monitoring.

Key Features

• Specific-fit Bosch Engineered Oxygen Sensor for direct application matching
• Narrow-band heated O2 sensor with 4-wire configuration
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Square connector with male terminal and harness included
• Standard replacement grade for OE-style service
• Built with a metal housing and high-temperature-resistant materials

Product Line Details

Bosch Engineered Oxygen Sensor parts draw on Bosch OE development that began with the original oxygen sensor design in 1976 and later advanced to planar narrowband technology. That engineering focus supports faster sensor response, improved lambda accuracy, and quicker closed-loop operation across changing engine loads.

Detailed Description

Part number 13275 is designed for vehicles that use a narrow-band heated oxygen sensor with a threaded mount and square 4-pin connector. Bosch uses optimized heater control and ceramic sensing elements to maintain consistent signal output under heat and vibration, helping the ECU manage combustion and emissions control. This Bosch oxygen sensor is a direct replacement choice for many Chrysler Concorde, Dodge Dakota, and Jeep Cherokee applications, along with other Chrysler, Dodge, Plymouth, and Jeep models listed below.

This part cross-references Monroe Shocks & Struts (e.g., 4605654, 5233088) for the same application.

Installation Notes and Tips

Confirm the sensor position before ordering: this Bosch oxygen sensor is listed for both upstream and downstream locations depending on vehicle application. Match the connector shape, wire count, thread size, and harness length to the original sensor, and inspect the exhaust bung threads before installation. Use proper oxygen sensor service tools to avoid damaging the hex or wiring.

Quality Assurance

Bosch backs this oxygen sensor with more than five decades of OE development experience. The design uses durable sensing materials, heater control, and thermal-resistant construction to support consistent signal output in demanding exhaust conditions.
