Most of the rings got lost, misplaced or did not ship with the B series ITBS from OBX. I found a set with the ring and 3d printed a replacement out of 100% infill ABS.
I do not know if this will work for the other Individual throttle bodies offered by OBX. Has only been tested on the GSR, B16/Type R and LS B series throttle bodies.
