Good point. I've always taken them off b/c I was taking the exhaust down on the race car or something so I needed to preserve the sensor.

Thanks!

and I am not so sure I would have the guts to cut them - if I stripped it or could not budge them - at least you could drive the car to someone else with the wire intact, - "i dont know, it was like that......"

I can *always* budge them, b/c MAP gas.

I replaced two pre-cat sensors on my M54 3.0. The tool and two sensors were under $100 and took about 30 minutes. It did actually give me a small improvement in gas mileage. If the job was much more than $100 though I probably would have just waited for them to fail.
