o2 sensors

why does it seem like Jeep 4.0s are notorious for killing oxygen sensors quickly? Is it just the wetness here on the east? I have never seen something go through so many o2s

any fix out yet? super dupper strong one, relocation etc?

My mothers XJ has 160k on it and original 02's... and my XJ has more than that on what I believe to be original 02's.... but the ones in my TJ look rather new.

it might be the weather... but they are a sensitive device... they also have crap quality control for them. Lots of bad ones make it out into stores.
