I just purchased a used Tial BOV. It didn't come with an O-ring that's used when connecting the BOV to the charge pipe. Does anyone know if that's necessary to be used?
Also, it came with some washer-type bolts (don't know what they're called). 5 of these "bolts" are marked "ASD" and 1 is marked "AKC". Does anyone know if these have to be used anywhere? I'm not sure what to do with them.
