93 D16Z6 O2 sensor thread size?
 

I've searched several forums and I've read that it's M18x1.25 and M18x1.5. Anyway, I'm wondering if anyone can tell me which of these 2 is the correct one. I'm wondering this so I can buy the correctly sized tap so I can restore the damaged threads in my O2 sensor thread. Please help me good people! https://honda-tech.com/forums/images/smilies/emsad.gif

Thanks, but unfortunately, now I can't find a tap that's M18x1.25! https://honda-tech.com/forums/images/smilies/emsad.gif All I can find are ones that are M18x1.5, or M18x1.50. Could I just use one of these instead, or do you know of a place that sells the M18x1.25 size tap?

Snap on, Mac tools, KD tools, SK tools, etc....

They all carry these tap and die pieces and kits.
