Thanks Koozy. I am torn. An aftermarket oil cooler is ~$550 I am just lookin for options. Can't we install this down the line a little bit? I keep overheating my FiST doing uphill driving. I realize this might have thermostat issues if I install in the wrong place. Do you think mishimoto will sell the part solo ever?
again... it's not worth it if you're not going to remove the stock oil cooler, which is a large contributor to high coolant temps. Adding an oil cooler and not removing the stock cooler only delays the time to reach high temps. Best to just get rid of the stock cooler and replace it with an air to air oil cooler. you can put together your own kit and not have to spend a lot. there are universal brackets available from some oil cooler mfg. like Setrab and Mocal that you can make work. You also don't need steel braided lines.
the hardest part if finding the adapter fittings to get rid of the stock cooler. Mishi won't sell it because that would kill their oil cooler kit sales with people building their own kits for a lot less than what they are selling for and they know this.
here's what I think might work for an adapter fitting to eliminate the stock cooler.
Once the stock cooler and it's adapter fitting are removed, screw this 3/4x16 fitting in to allow a oil cooler sandwich adapter to fit on.
then install this fitting (3/4x16) with the sandwich adapter to allow the oil filter to screw back in place.
