Replacing O2 Sensor

How to remove an 02 sensor while minimizing risk to the threads of the sensor/exhaust. No matter how "new" the sensor is, I ALWAYS recommend torching (in a safe manner). The amount of $ you'll use in torch fuel is light years cheaper than a new sensor. If you damage the threads of the sensor AND the exhaust, you're going to have a bad day 😤 | Poor Man Mods
