Review on 🚗 O2 Sensor Upstream/Downstream 234-4169 for Lexus GS400 LS400 SC400 LS600H LX470 LX570 Toyota 4Runner Land Cruiser Sequoia Tundra by Cody Howard

There was a delay with the Denso O2 sensors, so I got this one instead. Looked good quality, fit perfectly (I drive a 2003 Sequoia) and solved my problem. It was also about $10 cheaper. This saved me about $200 having a mechanic do it and took about 45 minutes of my time - well worth it. If I did it again today, it would take me half the time. It comes with a plastic cover - tip - leave the plastic cover on until installation. It protects the sensor from vapors and particles entering its inlet ports. Also spray some WD40 on the OLD connector to make it easier to pull it off the wire harness. That would easily save me 15 minutes.
