Bosch 13029 Oxygen Sensor

Bosch Oxygen Sensor 13029 Overview

Bosch Engineered Oxygen Sensor 13029 is a specific-fit, narrow-band heated O2 sensor built for stable air-fuel-ratio feedback to the ECU. It supports closed-loop fuel control across changing operating conditions and is a direct replacement choice for a wide range of GM applications, including Chevrolet Impala, Buick Regal, and Pontiac Grand Prix.

With Bosch OE development behind it, this sensor uses a ceramic sensing element, optimized heater control, and high-temperature materials to maintain consistent signal quality in demanding exhaust environments. The Bosch 13029 is a practical replacement for downstream and selected upstream positions where accurate lambda feedback matters.

Key Features

• Specific-fit Bosch Engineered Oxygen Sensor for direct application matching
• Narrow-band heated design for faster light-off and quicker closed-loop operation
• 4-wire configuration with square connector and pin terminals
• Threaded mounting with 18 mm thread size and 22 mm hex size
• Metal housing and high-temperature-resistant construction for exhaust durability
• Wiring harness included with 19.1 in harness length
• Fits downstream and selected upstream positions across multiple GM platforms

Product Details

Bosch 13029 is part of the Bosch Engineered Oxygen Sensor line, a product family rooted in Bosch OE oxygen sensor development dating back to the original sensor designs introduced in the 1970s. This line focuses on accurate exhaust-gas feedback, stable heater performance, and reliable signal response for modern engine management systems. For drivers searching for a Bosch oxygen sensor for Chevrolet Impala, Buick Regal, or Pontiac Grand Prix, this part number provides a direct replacement solution with OE-style construction.

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

What It Helps Address

• Check engine light caused by oxygen sensor signal faults
• Rough idle or unstable fuel trim from inaccurate exhaust feedback
• Reduced fuel economy from delayed closed-loop operation
• Emissions test failures related to sensor response or heater issues
• Slow sensor switching in high-heat exhaust conditions

Installation Notes and Fitment

Install Bosch 13029 in the threaded sensor location specified for the vehicle and position. Confirm connector shape, wire count, and sensor placement before installation. For fitment searches, this part is commonly selected for downstream applications on Buick Century, Buick LeSabre, Chevrolet Impala, Pontiac Grand Prix, and related GM models, as well as selected upstream positions on Camaro and Firebird applications.
