This AUXITO set includes both the upstream (front) and downstream (rear) oxygen sensors for your Toyota Tacoma with the 2.4L, 2.7L, or 3.4L engine.
If your check engine light is on for O2 sensor codes, or if you're experiencing poor fuel economy, swapping both sensors at once is a smart move.

Each sensor is heated, has 4 wires, and is a direct plug-in replacement (part numbers reference: 213-2857, OS1514, and others).

They're designed to restore proper air/fuel mixture monitoring and keep your engine running efficiently.
