I managed to get it working as a temporary replacement until I got the OEM part. The way the aluminum tubing is formed introduces possible stresses in the joints which I find unacceptable. I suggest avoiding this element, at least for the 2014 Optima. The OEM part fits perfectly, although it's a bit more expensive I'm sure it will serve you well. Please refer to the OEM part on the right in the attached photo.
