Theres this small o2 sensor near the bottom of the 3rd gen's dp. I was wondering what size that thread is for that o2 sensor cus i put on a KO racing dp and now i have no place to put that o2 sensor so i guess ima have to weld a bung into my exhaust pipe.

thanks a bunch u guys

O2 sensors are all one size of thread. from aston martin to zonda, its the same bung and the same thread its one of the only things thats the same between all cars.

Im pretty sure the pitch is different from the one of main o2 sensor, diameter probably too. Im pretty sure that you don't even need the secondary o2 sensor because few people with gen3 that i know of run without it.

Its not an O2 sensor. Its a cat/exhaust overheat switch that lights a warning light on the dash of the JDM ST205. Unplug it and throw it away if you have a downpipe.
