O2 Sensor Shield

Im about to replace my O2 sensors and have a quick question.

I can grind the shield off pretty easily, however I dont have a welder toput it back on and Im wondering if its even worth it. How necessary is this shield?I do some minor off roading, etc...
Thanks.

 

I got frustrated when trying to replace the sensor and just cut mine off. It's pretty flimsy so i doubt it would actually protect the sensor if a rock or something got up there.

I'm going to make a new one that will be stronger. The o2 sensor does seem pretty vulnerable up there so you probably should protect it if u take it offroad.

 

why not just loosen the two bolts holding it? They hold the O2 sensor also. Mine needed a little lube to break them loose but once you find the right wrench to get over the awkward angle they come off pretty easy.

 

I had to basically break my shield away from the sensor because the nuts holding the sensor in were almost completely stripped. Basically bent it outta the way. I see nothing bad happening if its gone....just make sure its smooth so it doesn't cut the sensor wires.
