Proper Placement of O2 Sensor

[EagleMark]

When installing an O2 sensor in a car that never had one or when replacing the exhaust system there's a couple things you have to remember.
First is you want it as close to the exhaust manifold as possible so it reaches operating tempreture. within about a foot is fine.

Second is you want it facing up, not down. This is so any liquid in exhaust like condensation or flooding does not have the ability to "Wick" down into the sensor. Always point so it drains would be a good way to remeber.
