I was wondering if there is a three wire o2 sensor I can use that just screws into a weld bung. I am having my downpipe rewelded and flanged and I want to replace my o2 sensor. Problem is that I dont have the o2 flange anymore so I am having my exhaust shop weld a screw in bung to my turbo elbow,yes its steel and no I dont want to wait to get another weld flange for the o2. I just want to go to advanced and buy a o2 sensor screw it in and go. Any help would be appreciated. Thanks
