What would be the point in fitting a raised air intake if the first time you drive into water thinking you are safe because the air entry level into the engine is at the top of windscreen level but you suddenly come to a stop with a bang because you haven't sealed everything below?
Any decent snorkel kit comes with instructions. And an important instruction is the one that tells you to remember to seal any drain holes in the air box...

As for blocking intake with rags/bags/towels etc etc... not a hope in hell, my guess is that there would be that much intake suction anything that was put over intake would cleanly get sucked in.... with your undies [tonguewink][tonguewink]

I could believe it. I used to have a 1966 Jaguar S-Type with a 3.8 litre straight six in it. It had an auto choke but it didn't work, so to start it, I'd lift the bonnet and partially cover the air intake with the palm of my hand while pressing the starter solenoid on the wing. A mate watching me one day asked what would happen if I covered all of the tube. I said it would probably stop. So I did cover it. It did stop. AND it bloody hurt the palm of my hand when it tried to suck my hand in!
That was only on tickover. I don't think parking a buttock over the intake of a big diesel screaming it's head off would be a good idea...

I think you'd find it almost impossible to push hard enough to stop the exhaust coming out of the pipe. It would be at high pressure, plus it might not be able to breathe while you are doing it.
Then there's a chance if it all goes Pete Tong up front, that there might be some lumpy bits being fired at you, mortar style

I love watching mummies sitting with a car full of kids on a hot day engine running AC on and not moving all the while sitting in a cloud of carcinogenic smog.
Pollution levels in big cities have increased dramatically in the sub 10 micron and 2 micron range, mostly attributable to the increased numbers of diesel vehicles.
Australia has the the second highest level of sulphur permissible in fuel as well. And we wonder why we have one of the highest levels of Asthma in the world?
Just look at any of the modern diesels under hard acceleration and convince your self that they are not killing us in droves

Bring on electric cars.........it cant happen fast enough

And yet governments told the people to buy diesels...
I drive a Disco 1 with a 300TDi because I really couldn't afford a V8's slurpings. When I bought it it was my only car on the road. Now it's my play time toy, but I also find it difficult to fight the attraction to wade in deep water. Something which you can do in a diesel and not have to worry about the spark going out.

The mechanic shoved a phone book on the intake and that stopped it. He told me never use your hand or it can actually suck the flesh of it. True or not, i dont want to try it...lol.

Given how much my hand hurt after doing that on the intake of a 3,8L jag straight six engine on tickover, I WOULD believe.
And the sad thing would be if your skin came off before it stopped, I doubt the bony bits left would form a seal so you'd be skinned AND your engine would detonate...

They are reducing pollution where they drive.

I'm guessing it stands for something?

Return on investment looks like the only ZERO thing there.

Motor vehicles account for around 8% of Australia's emissions, the big killer is our electricity production, you know all that nasty coal being burnt. Add to that we export 3 times as much coal as we burn. If Australia (if we actually had a working Government) was serious about our health and that of the planet we would stop burning coal and stop selling it.

Again if Australia was serious about our health they would get rid of Australia's fleet of aging old emissions spewing trucks that are used as inner city deliveries and wharf to distribution centre deliveries. This is where real world answers lay in such hybrid and electric trucks from FUSO / DAIMLER, not pie in the sky bull**** from tesla.

They were not sold as a snorkel. I read somewhere that the RAI was an attempt to reduce the percentage of intake air taken from the dusty heights below about 1.2m, thus improving filter life in dusty environments.
Apparently Nissan and Toyota had similar offerings.
Of course, it wouldn't be the first time car manufacturers have tried to latch onto an image, using gear that is not what it seems.

Hey Disc_Rob
I'm not sure if you missed my point. The standard air intake on the D3(&4?) is NOT sealed. The trunking between the air intake on the side and the air filter box is slotted and is covered with a cloth sock (presumably to act as a bit of a pre filter). Even the elbows have holes in them. The LR RAI just bolts on to the outside of the vehicle. RAI's are not sold as water wading devices, they are designed to pick up cleaner air and to increase air flow into the engin (LR specifically state this). That is why blocking the air intake on factory vehicles will not starve the engine. As you say though, decent quality brand snorkels such as Safari are sealed. The merits of using snorkels to increase the water wading depths of these vehicles is a whole different kettle of fish... [bigwhistle][bigwhistle]
