Today I did some work on the oil cooler air flow louvre. I want to be able to regulate the oil temperature on cold days, and this louvre from Anti Splay Aero should do the trick. I have a control cable running back in to the cockpit. Normally the louvre will be wide open, but on cold days (if the oil temperature is sitting too low) I can close off the airflow through the oil cooler.
Pictures below show how I mounted it.
Air flow open = cool oil
Air flow closed = hot oil
Mounted on the firewall, with control cable fitted
