If they are lazy or slow, they need replacing. It does happen sometimes. They should be able to tune WOT, since the O2's aren't used then.

Mine got tune w/ these O2 sensors.

You can use them, but they're complained about often. I decided to just get O2 extensions after hearing numerous complaints about the Bosch 13111's and how slow they are when compared to stock or Denso O2 sensors. They have a very bad reputation with tuners. When my stockers go, I'll pick up a set of Denso's. Everything Bosch makes is junk.

My Delco's would always throw poor heater performance codes & would be real lazy at idle... Put some of the Bosch's in & they switch 100x's faster at idle then my delco's ever did.

Yeah the Bosch are junk. Run the Densos and you will be fine.

I love how in 6 months the Bosch 13111's can go from being the main thing recommended to run to being touted as horrible. lol.

X 2...

When I bought my longtubes and researched what O2 sensors everyone used and what everyone recommended, the definitive answer was......(drum roll please)......yup, BOSCH 13111's...

now they're junk...

Got my z28 tuned with them. My tuner said one was lazy. So i went to autozone and exchanged the lazy one for FREE!!!! Id try that.

Well, think about why. It was discovered that the Bosch 13111 Corvette rear O2's work with the f-body. It was hailed as a convenience thing - no extensions needed after you go longtubes. People just assumed this was the way to go as you get a new set of O2's that are long enough to work with headers. No one really had any feedback on them. They were just praised for the convenience. F-bodys weren't being tuned years ago like they are now. Tuners didn't do much with them when they were under warranty since the cars weren't really modded enough that they'd need a tune. Now that all the warranties are gone, the aftermarket is exploding with these cars.

Now that the feedback started coming in, tuners started to see how much of a problem these O2's are. They don't last nearly as long as the stock O2's, the heaters seem to be weaker, they typically switch slower (that's not to say people haven't had good luck with them, but they have a much higher problem rate than AC Delco or Denso O2's)...so now they're discouraged by tuners. It takes a while for experienced people to pass judgment on the product. Tuners don't like them. That should say something about them.

When my O2's go, I will be putting in a set of Denso's. Denso plugs came in our cars stock, correct? Because I bought my car with 24,xxx miles on it, so I assume the plugs were stock when I changed them - they were Denso's. I pulled them out at 45,000 miles and switched to NGK TR-55's. I may as well have kept the stock Denso's because they looked brand new! Denso makes some great quality stuff, unlike Bosch, which is typically junk.

My Bosch wiper blades are nice though Over a year and still look brand new, driven in rain and snow.

Funny, I spent a relative shitload on bosch wiperblades, and they suck donkey nuts. less than a year later they didn't work well. Should have gone Kmart generic. Maybe you got a good pair, lol
