I am going to need to retap the o2 sensor housing on my new Hotshot header. Either the o2 sensor was messed up when it was put in on my old Stillen header, or, God forbid, I crosstreaded this one. What is the tread count (or number) of threads for the O2 sensor?

1999 SE Limited: JWT POP, NGK Wires, OBX Muffler 2.25" exhaust, Hotshot header, Eibach Sportlines, KYB AGX, 17 deg. timing
