savington,
So you cut out the metal in between, then mounted the cooler there" I assume air passes through it from the heat exchanger chamber, then out through the bumper, under the hood?

There is no ducting to it. Relatively no airflow. Don't have to cut metal, just get rid of the plastic bumper beam under your bumper skin.

Why don't people mount a couple of 12v 120mm PC fans to their oil coolers and rig a switch to the centre console? If you're running too hot, turn them on at the track. No cutting of bumpers required. Or am I missing something?
