My 94-97 RB header bung seems to be in wrong location for the WB sensor as it points down and likely will be too hot in the provided location. I am looking for suggestions from others where to install - people with 94-97 header - where did you weld the wide band sensor bung? Is it better near the flange ? I don't have the car now to check and fit and so doing some thinking where would be a good place to weld a new bung.

 

That looks like it was intended for narrowband sensor which you would retain unless you got a standalone. I have mine on a turbo application directly below shifting turret.

Also you could wrap the header to help with heat management.

What application is the car? Street? Track?

 

probably no issue there.

 

track car only , no cat and no narrowband. Waiting on DIY to release 97 MS3.
If you think farther from header is fine, since I am redoing the front pipe of the muffler that mates up to the header than i have a good location as shown on the pic. That's roughly would be in front of the CAT aid I was running one.

 

You want it to stay warm, so no, that is in no means too close to the head. By a long shot. It is, according to the sensor instructions, at the wrong angle however. I have installed widebands using that location, and it is very convenient for access, and they have lasted. I have also re-welded roughly in the same location, only facing straight up. Obviously supposedly better, but more work, and less access.

 

wrong angle because it's -10 degrees or more and may see condensation ? Given the pipe is slopes down, I think I'll try this. I don't want to put more holes in the header if I don't have to.

 

condensate is not going to pull on a vertical run...

 

i was thinking the offset angle on the RB bung location should be ok as its inside a vertical - I think you just confirmed it. Thank you Curly and Brain

 

You're welcome!

 

Thank you Ysleem. Appreciate the advice.
