I'd be concerned about heat dissipation. Maybe it's not a problem...

I think in reality, the sensor is perfectly happy as is. It's in a relatively protected place in the manifold when compared to later 240/740/940's where the sensor is in the CAT or the tail end of the head pipe. There, they bear the full brunt of road salt and debris, and they still hold up fine for almost 20 years and several hundred thousand miles.

Seems the contaminants going through the engine (e.g. bad fuel additives, rich running, oil) are more harmful to the O2 sensor than the outside environment.
