I ended up with both snorkel air rams:
I must have a play and see if they are different in the real world.
The paperwork with the air ram says you can reverse the ram if it is extremely dusty or is "very heavy weather", but "the vehicle speed SHOULD NOT EXCEED 25 km/h as it may cause damage to the engine."
I look at the stainless steel tube snorkels (usually on Patrols) with the opening facing backwards and wonder...
The install was done by The 4WD Workshop in Seaford, Victoria.
