Some follow on notes.
Make sure you leave slack in the hose lines to allow for any engine movement.
Fill the oil cooler and the lines with oil before connecting them to the oil thermostat. This can be tricky with bottom outlets on the cooler. I connected one hose line to the cooler and flipped it upside down so I could add oil to the cooler. When the cooler was full. I then attached the second line to the cooler, flipped it over and bolted it in place. I then filled the hoses with oil before attaching them to the oil thermostat. The cooler and hose lines took almost a quart of oil so there will be 8 quarts of oil circulating instead of the factory 7 quarts.
I kept the factory oil thermostat so the engine would heat up the same way as an N54 engine would. The thermostat starts to open at 240 degrees which is just what I wanted.
Its been too cold in Florida to test the new install so I'll have to wait until things thaw out to find out how well cooler will work.
BTW, the whole installation cost me less than half the cost of the BMW cooler.
