Looks like I have to buy a front left O2 sensor since I threw a CEL 1001 over the weekend. I reset the ECU but it came back again today. My question is what brand does everyone usually get as a replacement? This site https://www.automedicsupply.com/catalog4.php?PHPSESSID=697ecc5ea23585a4317d8a7f94cf5de2# shows 3 brands listed for OEM fitment; Walker, Denso and Bosch. I just want to make sure I get the better of the three brands. Thanks for the input.

Ok, thanks for the info guys. What's the normal life expectancy of a typical O2 sensors? I'm at 75K right now so would it make more sense to buy the the front right sensor as well since I be down there changing the left one? I have already changed out the rear O2 ~15k ago so that one is good but the current left/right front ones are still the factory ones.
Sounds good Jeff. I don't want to spend money when it's not needed. I just didn't want to change this O2 and a month later have to jack the car up again and swap out the other. (Time is money as well.) These little things always seem to come up after I install a new mod that is totally unrelated. (DTM replaced GenII Altezza and Mag-Lite Mod in trunk.) Maybe its my car's way of telling me to stop and to put it back to stock? (No chance.)
