We have found this to be adequate cooling
for the DA170. Depending on your engine’s
operating temperature, you may need to allow
for more exit air cooling for your engine to run
at its recommended operating temperature.
Always check the operating temperature of
your engine to prevent any damage from
occurring. Aeroworks is not responsible for
damages incurred from improper engine
cooling.
