Last night I had some of my intake piping apart, and noticed that there is a threaded hole, presumably a mount for something, that doesn't have a bolt to go on it.







The area surrounding it looks slightly less grimy than the rest of the y-pipe, so it seems like something was attached there recently. Can someone tell me what is supposed to mount here?




Thanks,

Nothing! I have 2 93 fds and there isn't anything there on either one. Maybe some JDM option. It appears to be just a mounting point, nothing functional.

 

Thanks, PhDMDRX7.

 

There is a clip there that holds the O2 sensor wire.

 

yup

 

That explains why that hole looked clean; I swapped in a wideband O2 sensor a few months ago.

By the way, that's a great-looking car, EFS.O
