I didn't break one, I need a couple to complete my N20 plate install. I guess they are the correct thread/size to replace my studs coming from my intake that holds the throttle body on. I'll give the dealer a shot, thanks.

They are 6mmx1.00 and about 2 3/4" long. Not sure how well they will work to hold a TB on though.

Thanks for the pic! .... does the bolt unthread out of that cylinder or is it all one piece?

NP. It doesn't just thread out. The spacer seems to be crimped on. I'm sure with a well placed dremel, it would come off pretty easily. Not sure how far the threads go up though.
