Since I'm going to mount it low and exposed on the front bumper, I'm actually looking at a CSF unit now (8066) which is 22"x5". They are expensive, but have two advantages for my application: more bullet proof for exposed and low front mounts and side ports for an easier and cleaner hose run on same application.

Regarding where the temp is available, The Foxwell or other software will tell you real time info, but the car won't that I'm aware of. I think other models have modes that will, but not the E53 I think. I've got a 4.8 cluster now and it has the oil gauge in it. I need to find out where the sensor is though for a better understanding of the system.
