I need some feedback on 02's if anyone knows anything about the 2 options i have,
here is the stock OEM Bosch this is what MB replaces them with when they go bad, (mine have gone bad twice already)

here is OEM with MB box but $45 more for each one.

here is my 2nd option this is the Walker O2's more money then Bosch but they say they work better then OEM

(WALKER PRODUCTS OXYGEN SENSOR -- A high quality, direct fit OE replacement oxygen sensor; Improves car's engine response and gas mileage; Effectively lowers emissions upon replacing its tired old oxygen sensor; Exceeds OE specifications and test requirements.)


i check my o2's with the Autoenginuity and one of them is fried, samething what happened last time i went to dealer, they replaced the fried one and rite away the one that was good fried and then started getting misfire codes.

any input on whats better to use for longterm would be great

Do you know why you have problems whit 02 sensors? Will you get a CEL when they are bad?

Mort

Are you using leaded race gas? This can really shorten the life of O2 sensors. I am sure hot lapping is hard on them as well as heat is also a killer. Sorry I have no experience with different sensors.

mthis

yes i use race gas sometimes, no CEL for me, but do feel a lil shake here and there, so that led me to check them out and found 1 fried, maybe cel comes on after both a fried.
no leaded race gas for me just VP unleaded street blaze
i also think the heat is getting to them, thats why next set thats going on i will put 02 sim maybe they will help
