Hello yall, I just wanted to share a quick DIY on how to just make your own oil cooler kit for the low. Since I also have a G37X the sandwich plates that oil cooler kits come with have the inlets facing down which scares me as it becomes a low point of potential damage occurring if I hit something on the road. Instead, I just did it on my own and also saved a few hundred dollars. The only time-consuming part of this project was doing the AN fittings onto the braided hose. Since it was my first time it took a few trials until I got the hang of it.

Previously without an oil cooler during the summer here in Texas my oil temps were at 220-230F. After doing a pull it would reach 235-240F. After the oil cooler, the highest the temp has reached was 203F then it coasts down and runs at around 194F.

First: I cut the bracket to the size of the oil cooler and you can place the oil cooler onto the bracket to see that the holes line up and you can put a nut and bolt through to hold it in place. Also, place oil into the oil cooler as a pre-fill you do not want to run low on oil.
Second: Get two extruded u-nuts and there is already a pre-hole on the radiator support that you will need to slip place the bracket and use two 10mm bolts to hold the bracket onto the radiator support. Then place the two 90 degrees AN fittings on. For all of the fittings, I did use Teflon tape just to ensure no leaking occurs.
Third: I took the oil filter out and placed the sandwich plate onto it. In the image, you can see how I have it set up which is faced upwards and it seemed to work the best in my opinion. I connected the 120 degrees fitting on the top and the other 90 degrees fitting on the bottom.
Fourth: I grabbed the braided hose and mocked it up by placing it first on the closest 90 degrees fitting from the oil cooler and basically positioned it how the line would route to the sandwich plate fitting. I marked it with a sharpy and always gave myself an inch more if I messed up on the cut I still have more material left before it gets too short. Then I repeated this process to the furthest fitting on the oil cooler and marked it with a sharpy and went an inch longer for any mess-ups. Make sure to give yourself an inch or two inches more especially if it is your first time.
Fifth: I cut the hose to size with a thin cutting disk since it has metal in the hoses. There are many youtube videos that show how to do this process. Just make sure the end of the hose is as straight as you can get it. Mine were not perfectly straight but as straight as I could get it using a grinder. Also do not forget to clean out the inside as it will have a debary inside from the cut.
Sixth: Place the fittings on the ends of the hoses and route the braided hoses and you are done. I used a lot of zip ties to hold it onto the crash bar so there is as little movement as possible. Do not leave your lines hanging because when you drive the lines will start to move and could start rubbing onto sharp edges and cause premature failure and cause a leak.
Seventh: Make sure to check your oil dipstick and add another half a quart of oil as oil will take place of the hoses. Go for a drive, and double-check to ensure no oil is leaking.
