This is the plug that is in my cobra oil pan and I wondered if it is the original assembly line item?

It looks like a replacement.

+1 Definitely a replacement/stand-in for the original

Looked but don't have a picture of an original handy and in the computer to post at the moment :(

The oil plug that you have is a replacement plug designed to "fix" a stripped out internal thread. The tapered shape with slots re taps the  stripped thread so that the plug can once again be tightened securely. At this point I don't believe that you can go back to a standard plug because the internal thread created by this plug is larger (diameter) than it was originally even though it has the same thread pitch as your original plug. A helicoil might be a possibility but I would re drill/tap the oil pan for a larger (thread) plug. I had to go this route on my pan many years ago.

I'm sure that you didn't want to hear what I just said.

Sorry

I would rather know the truth then to lie to myself...LOL.  Does anyone have an original plug they would be willing to part with?
