About the backwards facing snorkel conundrum

[Sergio Castro F]

Reading your very precise and scientific metod of measure this issue, and after read opinions about different kinds of climate and uses around the world, and the fact the Land Cruiser come with a 2 air filters (paper cartridge, and ciclone in the same system), can I conclude the best way is to use it forwards,except the event of a severe snowstorm, a very narrow jungle track , or as we can see in some off road competitions that vehicles makes fords at very high speeds. There's another fact, the snorkel scoop of the Safari and Airtec brands comes with 4 holes for water exit, instalation manuals said. Congratulatios for the experiment and the opinions and the debacle between the readers.
Excuse all for my very basic english, is not my mother tongue too ¡¡¡¡¡¡¡¡
