Front Air Fuel Ratio Sensor


2001-2004 Tacoma, Tundra's and 4runners use a AFR “air fuel ratio sensor” up front rather than a 02 Sensor. Will also fit 00 Tacoma, 99/00 4runner with California Emissions. Its a good idea to replace the AFR at the time of swap, We highly recommend these OEM Denso AFR's This is a much better option than a aftermarket, or bosh replacement AFR sensors that we have seen issues with.
