Review on 🔌 Denso 234-4622 Downstream Oxygen Sensor: Black, 4-Terminal Plug – Ultimate Efficiency by Jason Hayes

This part fits my 2008 Japanese Rav4 Base 4 Cylinder Engine (Low Flow Sensor, Bank 1, Sensor 2). The check engine light went out and hasn't come back on. The plug was a perfect fit and the cord was just the right length. The only thing I didn't like was that the part had to come in a sealed bag with an anti-seize agent on it. I'm pretty sure someone ordered the part and it didn't fit their setup and returned the part by opening the bag and saving the ingredients. I wonder what would happen if I tried to return a part I originally wanted to make, but it was obvious the part was unused and I needed to fix my rig. I had to spend another $4 for an anti-seize compound that would last the rest of my life. Hence the four stars.
