02 extentions

[Anti venom]

just orderd longtube qtp headers and forgot about 02 extentions. i am useing the non cated y pipe. so my question is do i need to still get the 02 extentions?

Extensions or Bosch 13111 O2 sensors. The Bosch sensors have a nice long harness.

so i do need extentions no matter what right?

The O2 bung on the LT's is back by the collector. No way the stock harnesses will reach them.

I would run the longer O2s (bosch 13111s) instead of the O2 extensions. I ran extensions at first and kept getting weird readings....switched to the 13111's and havent had any problems.
But to answer your original question, if you keep the stock O2 sensors, you will need extensions for any LTs.

Out of curiosity, how much does one of the Bosch 13111s cost?

ebay has them for $46 + shipping....they're ~$75 at a parts store.

I paid about $180 with tax for 2 Bosch 13111s at the local NAPA

[pajeff02]

I think they were around $73 each at Autozone.

I have one brand new in the box that I forgot I had and went to buy another one. PM me if interested.

I read you can use Corvette O2's, this true?

Yep, thats what the bosch 13111 are (have a longer wire, so you do not have to use an O2 extension)

[Y2KPewterSS]

So $100-150 approximately for 2, or $30 for a pair of extensions?

yeah, but you get new O2's out of the deal and the word on the street is that they do a better job of keeping heater codes at bay than the stock sensors. I'm not going to say they do or don't work for that but I was throwing heater codes on a regular basis until I put those in and now I'm at 2 years without a single code.

I would certainly buy them if my 02s were bad, but I don't think I could justify spending another $100 or more to buy them if the current 02s were in good working order.

The problem though is that O2 ext. tend to have more issues with inaccurate readings. I thought they same thing when I got my LTs, save some money and buy ext. with stock O2 sensors. I kept getting weird readings, finally decided to switch to the 13111's and havent had issues for the past several years. Most ppl I know running ext. eventually switch to the longer O2 sensors as well.

We are just recommending the 13111's now so you would only have to be under the car once, and will most likely end up getting them down the road, so save yourself the $30 in the end.

I'm learning this lesson right now. I used extensions and flip a heater code every day. I turn it off...it comes back. I'm on the way to get some 13111's tomorrow, thanks to this thread.
