Review on 🚗 KAX 250-54051 Upstream Oxygen Sensor: Compatible Replacement for Tacoma and 4Runner O2 Sensor by Justin Olson

do not repeat my mistake. Read other reviews and laugh. I bought and installed this O2 sensor on my Tacoma 03 (Denso brand was double the price). At first I found it very difficult to insert the connector into the latch. After installing the sensor the truck seemed to run fine, I skipped a full heat cycle without the check engine light coming on or stopping operation. The next day I drove to work and noticed that my truck lagged behind when accelerating. I have already ordered a Denso O2 sensor and now I need to reinstall the O2 sensor.
