This is good work. I am not trying to cast aspersions in any way here. Morgan Motors chose this design in order to pass certain EPA emissions tests regarding noise levels and the easiest way was to choke off the engine air. Part of the problem was the noise from the incoming air flow. I replaced the stock hockey puck as the engine couldn't breathe properly, in my estimation. No regrets. Far easier to just replace the air cleaner housing with something that allows air to flow.
I chose the 'Muscle Air Cleaner' from S&S and it has worked like a champ!
As for water ingress and driving in the rain that has not been an issue. The S&S rain shield fabric wrapped around the air cleaner filter does a very good job in removing, or reducing, the size of the water droplets entering the inlet so that is not an issue.
Final thought. The stock filter cover is a crappy design and deserves to be shelved. There are others out there that work quite well and don't need to be machined anew!
