Review on 🚀 Denso 234-4163 Oxygen Sensor: High-Performance Monitoring for Optimal Engine Efficiency by Todd Foster

After finding the old one on Grandpa's Siena in 2002. I had to remove the passenger seat to find a cable clamp that pushed the cable through the rubber boot hole. I used the O2 sensor socket to remove the sensor and get rid of all the rust from a broken bolt, but still managed to do it. This sensor comes with a paper/metal gasket which I tried on several times until it was tight. I had to remove all the rust. Spray with rust remover and clean with a wire brush. The sensor fits well and firmly. Removed the sealant/epoxy applied by some bad mechanics after I tightened the bolt, it held the sensor firmly in place and sealed it all around (very important). Also the code for this sensor is gone.
