Hey guys, I am fabricating a test pipe for a B14 with an SR20DET. Does anyone know off hand the thread pitch of the rear O2 sensor? I don't have the car with me right now and I need to know so that I can go buy a nut of the right size. Thanks a lot, ===== Jay Whitely Tampa, FL 1996 200SX SE-R GTi-R powered, F-MAX Stage 2
