Spectra OS6327 Oxygen Sensor - Downstream Left or Downstream Right

Spectra OS6327 Oxygen Sensor Overview

The Spectra OS6327 oxygen sensor is a direct-fit emission control replacement for select Toyota applications. It is built with engineering, manufacturing, and quality control processes aimed at matching or exceeding original equipment performance in the vehicle’s exhaust monitoring system.

Key Features

• Direct replacement oxygen sensor for emission control service
• OE-style performance focus for accurate exhaust feedback
• Fits 2016-2017 Toyota Tacoma, downstream left
• Fits 2003-2004 Toyota 4Runner, downstream left
• Fits 2003-2004 Toyota 4Runner, downstream right
• Part number OS6327 for catalog and cross-reference lookup

Detailed Description

Spectra OS6327 is an oxygen sensor replacement for downstream positions on select Toyota Tacoma and Toyota 4Runner models. This sensor is used in the exhaust system to monitor oxygen content after the catalytic converter, helping the engine management system evaluate emissions performance and fuel control strategy. For buyers searching for a 2016-2017 Toyota Tacoma downstream left oxygen sensor or a 2003-2004 Toyota 4Runner downstream oxygen sensor, OS6327 provides a fitment-specific option.

This part cross-references Gates 24848 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor circuit faults
• Incorrect downstream sensor readings
• Emissions test failures tied to sensor performance
• Rough or inconsistent fuel control feedback from the exhaust system
• Replacement of a worn or aging Toyota oxygen sensor

Installation Notes and Tips

Confirm the vehicle year, model, and sensor position before ordering. This part fits 2016-2017 Toyota Tacoma, downstream left, and 2003-2004 Toyota 4Runner, downstream left or downstream right. Compare the original sensor connector and routing before installation, and inspect the exhaust threads and wiring path for damage or corrosion.

Quality Assurance

Spectra Premium states that its engineering, manufacturing technology, and quality control are used to produce oxygen sensors that meet or exceed the performance of the original equipment they replace. Part number OS6327 is cataloged for OE-style replacement use on the listed Toyota applications.
