URD MAF Sensor Calibrator for 05-15 Toyota Tacoma V6, 03-09 4Runner V6, 07-09 FJ Cruiser. The URD MAF Sensor Calibrator intercepts the signal from the Mass Airflow Sensor and remaps it optimizing the fuel mixture for the best power and performance. Had this installed on my Tacoma and has made it really responsive. The MAF Sensor is calibrated to Utah's altitude and aftermarket cold air intake. I have a S&B cold air intake. It's an easy 5 minutes install, one end plugs into the MAF Sensor and the other end plugs into cylinder #3 spark plug coil.
