      Replace Your Tacoma’s Lazy O2 Sensors. Oxygen sensors are integral components of your engine’s operation, monitoring the oxygen content of the exhaust to adjust the air/fuel ratios and timing for efficient combustion. Over time, factory O2 sensors often become lazy and inefficient, offering improper readings and negatively impacting engine efficiency and performance. If you suspect your Tacoma has a tired downstream O2 sensor, consider installing these quality aftermarket replacements to restore efficiency without emptying your pockets.

      Premium Sensors. These O2 sensors are constructed from premium double-layered 301 stainless steel, ensuring excellent heat and corrosion resistance. Both sensors are also plasma sprayed and isostatic pressed for extended service life. 

      Sold as a Pair. Whenever replacing O2 sensors, it’s recommended to replace them in pairs, or better yet, all simultaneously. For this reason, this kit includes left and right bank downstream O2 sensors, ensuring a balanced reading across both banks. 

      Direct-Fit, Plug-and-Play Installation. These O2 sensors offer a simple installation, featuring identical threads and form factors to the OEM components. As a result, these sensors thread directly into the O2 bungs on the factory exhaust. These sensors also feature factory-style electrical connectors, which integrate into the factory wiring harness without cutting, splicing, or modifying. 

      Warranty. A limited lifetime warranty covers this product against manufacturing defects. 

      Application. This O2 Oxygen Sensor Set fits 2005-2011 Toyota Tacoma 4.0L models.
