Front 02 Sensor
Its a good Idea to add new 02 sensors with your swap, we offer OEM Denso front 02 Sensors for easy install in swapped rigs. Works with all 95-00 3.4, 3rz, and 2rz swapped Toyota 4×4's. This is a much better option than a aftermarket, or bosh replacement 02 sensors that we have seen issues with. If your swap is from a 00 Tacoma or 99/00 4runner make sure you have federal emissions.
