Most likely they are the cheap china version of the BMW couplers, but I'm curious myself.

I sell Dorman through my work. I've looked at these and they're junk. Find a Beck Arnley distibutor and order 103-2218 for early 10mm or 103-2223 for later 12mm version. Made in Germany,stamped with BMW part number and top quality. Should be able to buy them for $50 each tops.

Also, I should use all new bolts right ?

Not necessary, and the service manual does not call for replacement.

They do not. I have a 99 and it does use 10mm. I'm not sure but I think after 2000 they switched to 12mm
