Default Plugging an o2 bung?
What is the best way to plug one. I know that K&N sells o2 sensor plugs, but is there anyway to get something without ordering and waiting 3 weeks? Or anyone else that makes a plug?

Just get a bolt that fits and cut the end of it off so it doesn't stick in too much. I think they may be NPT threads but I'm not sure.

I just heard that it was a bastard thread, and the local auto parts store could not find a nut to fit it. They did say that the closest thing they had was an oil pan bolt, but he did not want to open the package to see if it was close, or "it."

I'm a little embarassed to say, but after an all day search I found that a spark plug (large thread) works great.

Best thing about a 18mm X 1.50 drain plug is that if you care about asthectics(looks) for you unwashed heard the drain plugs fit flush and look sweet.
