Which or what model number is the o2 bung I'm gonna need to buy for the relocation on the obx headers/ypipe please?

 

18mm bung needed and bung plug got it. Ok now which bung on the obx header ypipe needs to be plugged and re-located 90* to the right? the one actually on the header or the next one down?

 

The header that is welded to the y-pipe that goes between the engine and firewall. Its the first 02 bung on the header collector. Turn 90 degrees so it faces the passenger side of the car once installed.

 

Then you have to make slack on the sensor wire so it will reach. Do this by carefully cutting the housing and the plastic box that surrounds the wire harness. Its next to the VIAS valve where you will put your NWP block plate. Then tape it back up nicely. Thats just what I did and there are pics here if you can find them. Will probably have to do similar for the front primary 02 as well.

Thank you very very much Toolbox! I remember seeing that thread but I couldnt find it again. So it's the first bung on the header of the y-pipe. Got it thanks!
