I am looking for a nut for my NTK o2 sensor that I got with my wideband. So far I went to ACE hardware, Home Depot, Menards and Autozone. No one had the right sized nut. anyone bought this nut before and know where I could get one?

 

go to an exaust shop

 

are they gonna have the nut?

 

are you talking about a nut to weld on to your exaust? If it is just call up an exaust shop and ask for a O2 bung.

 

I'm assuming that you want to install WB for tuning. Just go to any exhaust shop and have them weld an exhaust bung on to you down pipe close to the DP/MP flange.

 

Wow do I feel stupid

 

Are you talking about the bung plug that screws into exhaust?

 

I am talking about getting an exhaust shop to weld a bung to my midpipe so I can put my wideband sensor there.

Anyone know the temperatures the midpipe sees?

 

Hawt! :d

 

I don't know the temps at the MP. But the farther away from the trubos the better.

 

Mine is welded about 3 inches from the dp to mp flange. It is on the dp side. I've had my innovate wb plugged in for 5-6K miles now with no problems. I paid $10 cash at a local muff shop to have a bung welded in. I supplied the bung.
