especially as in a 90 I generally drive with the window open .
Think the last time I saw your 90 ! Mmmmm did it have windows ! 
Being left hand drive and enjoying the sound of a turbo in my ear I have quite taken to having the window down a touch so I can listen to it whine under load, better than the radio most days.Had it faceing backuds & it drove me mad

It will only make much difference on any vehicle if you can, or do, drive over about 55mph. This is because wind resistance increases logarithmically with increasing speed.
They aren't only fitted on 90s, they are also fitted on late model Discos, Freelanders, etc. Which are actually capable of speeds well in excess of 55 mph.
Fuel inefficiency at speed is also compromised by fitting rows of massive spotlights and light bars on the roof. As in the case of the chap who posted up recently complaining that his Td5 D2 was returning less than 18mpg at motorway speeds!

Like I said I really don’t care about performance, or mpg for that matter, the effect on either will be negligible, was only the filter getting damp and collapsing that bothered me. The Southdown doesn’t appear to have anything like the picture above, the scoop is to be bonded on if you go by the instructions so the only place rain can go is down the pipe.

many moons ago i saw a guy fit a drain tube on the bottom of his snorkel, but then when he went into deep water , tube filled up and straight into the engine , bang
in one sense i could see his thinking but alas cost him an engine
like many of us , we’ve seen very inexperienced people fit them , not seal it , then think they can go swimming
pic is one that’s been properly fitted and survived unscathed , is a member on another forum who does a lot of expeditions etc
wouldn’t have dared go that deep, up to the sills is deep enough for me

It is a particular skill of mine! I’ll get a spare paper one and see what happens, was bored in the hotel the night before a course doing some research on fitting it and came across some old threads talking about rain getting in snorkels and the mind wandered!Think
