The orig 9-3 oil cooler assembly with hoses looks like this when removed from the car

With the help of pliers and some force one can separate the engine side connector piece from the hoses
hoses intact:

The what you need is to have new hoses press-fitted into them.

I'm sure one could pick up a pair (orig hoses) from a junk yard from which you can take the parts and then the only thing you need is to find a local hydraulics shop where they can press-fit the new hoses.

Other option si to utilize the NG900 "leg" which fits plug and play to 9-3, but it has threaded connection to the hoses
Thread size is M20 with 1.5mm pitch. Please note that the hole is not "threaded" all the way to the bottom and many pre-made nipples will "bottom-out" before seal surfcase meet.
One way to solve the matter is to shorten the nipple

and to use copper seal for sealing

I can attest to using good oil lines and fittings, I tried to go the cheap route and had some issues with my oil lines leaking. I finally got smart and had some hoses made up at a hydraulic shop for about 35 bucks and they crimped the ends on for me. I feel much safer now.
