Installed not tested yet.
I have been driving with the engine lid open the last week and I do think helps overall heat in the engine bay, but, for test purposes I will drive the next week with the lid closed.
Open is much better but after a long hard drive between 90-100kph and running great it still suffered heat soak after parking 10 minutes and I had to wait 20min before it started and ran sweet again all the way home another 100km.
