What is the thread diameter and pitch for the o2 sensor on the rb header. I tried using a universal one and it blew out a couple of miles down the road. is the rb header maybe a little different? Any input would be great, i want my car to run tip top when the engine comes back. thanks

Should be M18x1.5

 

I know it's 18mm Can't remember if it's 1.5 or not.

 

should be a standard metric O2 sensor thread, wonder if the threaded fitting they installed at RB was wrong. coulda been built on a friday...


i have a universal in my stock manifold, the RB should also have the same thread so either they got you some oddball universal O2 sensor or the plug is incorrect, if you had it tightened down that is..

 

ok thanks, yea i had it tightened down . . i think. . lol I'll have to buy another o2 and check it out. if it doesn't fit i will have another bung welded in or something. . i dunno. thanks for the input
