We will be in touch
I have noticed that a good few of these seem to have an "exhaust" type thing coming vertically from the bonnet near the front of the driver door.
What are they for?
It's an air intake to reduce dust or moisture getting into the engine
Snorkel innit!
but they all seem to have an exhaust in gthe normal place at the rear, wouldn't that fill up with water?
ps if you already realised i know nothing about cars!
It's a raised air intake so the engine can function when crossing a river (or whatever).
Exhaust ok under water so long as you keep the engine running.
The back pressure from the exhaust, as long as the motor is going should hopefully provide enough pressure to stop water making it's way up the tailpipe.
They are there to look like a snorkel so the owner can pretend they go wading through deep water.
However, as the [url= http://www.aecmilitant.co.uk/downloads/101waterproofing.pdf ]full waterproofing instructions for the Forward Control Land Rover[/url] run to 107 pages, most of them are just for show.
They do help in dusty environments though, by putting the air intake higher up in cleaner air.
If you look at trucks, you'll see most of them have the air intake on top of the cab with the induction pipe running down the back to the filter.
It's so you can do [url=
( NOTE - don't try that at home - he was lucky to get away with it )
As said, in dusty environments it also helps to keep dust/sand out of the engine.
Some people also fit them because they look cool and expedition-ary.
