Easy to install - I love how they cap off 2 ports. I have only 2 tubes and I was planning to source a cap for the unused 3rd port and when I opened the box and saw the caps, I was quite happy I could skip this step.
Fan is LOUD but thankfully my engine is louder. I only hear the fan if I switch on the avionics without the engine running. This thing moves a LOT of air!

Q: Does it filter air? If not, is there a filter that could be put on it?
There is no provision for filtering built in. We suppose a piece of rigid filter material could be taped over the intake on the side, but that install would be at your own risk and responsibility.
