This is my opinion, both boxes above do not deserve to be called breather boxes. They are way to restrictive and far less effiecent compared to a original 1600 VW T1 box. Look at the total in-out area and compare it to the original one. A original box has a 19mm inlet (through the original alternator tower) and a 14 and a 12mm outlet where one has suction from the carb. This ecuals 5 AN8 fittings. I also do not understand why someone choose to breath from their valve covers but that is a other topic.
