I always assumed the Mantec is more for avoiding dust and spray and the Safari is more for scooping air and wading.
Isn't the Safari system more waterproof too, connecting directly to the air duct?

Safari are made for the inlet to be pointing backwards.

I can't remember where I read it but basically to get the 'Ram-air' affect from a Safari you would have to be travelling at something like 120-150mph. Plus ram-air doesn't work with turbos so pointless anyway.

If you seal a Mantec properly (Land Rover don't) it will be as waterproof as a safari.

Air filtration........ a snorkel helps but doesn't do a whole lot unless it has a pre-filter (safari) or have a centrifugal filter at the top. I decided to get one for mine and over the past year have emptied about 2 pints worth of dust/ sand out of it- but I am in a hot and dusty climate.

Either work as good as the other. Main things to do are

1. Pick the one you like the look of.
2. Fit and seal it properly..... your engine could depend on it one day!!!..... Plus it will just be a pointless piece of plastic if not sealed

Shhhh - do you think the others know?


Incidentally, driving around the dust holes Italy, I noticed a lot of dust piling up at wheel arch height but hardly any on the roof - I would like to believe the RAI did something  Tell someone you love them today because life is short.
But shout it at them in German because life is also terrifying and confusing...

I am sure it does help loads but if you are going to somewhere dusty I would defiantly recommend some form of pre-filter..... can cost as little as £30.

May I add to the confusion about snorkle heads.
I might be wrong but the way I see it is facing a ram head backwards is counterproductive, it is not only makes it harder for the engine to breathe, it also sucks in more dust.

assume the tennisball is your snorkle head, When the snorkle is pointing forwards (to the left in picture) it sucks in all the air (including dust) that is in its path.

When the snorkle head is pointing backwards (to the right) it sucks in the air which is also now also mixed with dust from the sides past the edge of the snorkle head , so its getting more dust when pointed backwards.

That said Ive done some tests with my Nanocom plugged in & the Mass Air Flow readings are pretty much the same, on the same bit of road at the same speed with the Ram head forward, back or off all together.

Ive found that absolutely the best RAI head for dusty outback work is the Donaldson style cyclone pre cleaner,enough dust gets in there to need emptying out once a week. But they do mike a fair sucking noise & gets annoying around town.

Basically I have 3 snorkle heads that I use, The Safari Ram head pointed forwards for interstate highway work, I get about 120 klm extra per diesel fill ups on the 850 klm Melbourne - Sydney run. ( I have 170 litre fuel capacity)
For general running about and doing construction site & bushwork I use a Toyota cyclonic pre cleaner, and for extended outback trips I use the Donaldson pre cleaner.

I have a Donaldson type (ARB) on mine permenently as I spend morte time off-road than on road. I empty it every couple of weeks in the summer. I know what you mean about the sucking/ whirling sound.... I just put up with it, lol

It really does open your eyes to how much dust would make it down to the engine filter if you didn't have a pre-filter of any sort

Just to sway this topic off line briefly but its that time of year again, insurance renewal!!

I got a reasonable renewal from my current insurerer but thought I would try Price comparison sites.

A certain pachyderm named site quoted £300 fully comp whoopee!

When I called them to confirm the insurance and mentioned any vehicle mods/extras when I got to the "Snorkel" they stopped me there and said they dont cover snorkels as I may off road the car !!!!

Indeed my current company, named after a senior naval rating, are actually a sister company of the aforemantioned, they could therefor look at my existing policy and informed me that I should have been rejected by them too as there was no mention of a snorkel!!

As for another rant, when I spoke to a company advertised in LRM as a specialist insurer, similar name to the county town of a Yorkshiremans nemesis, I was informed they did not cover vehicles with more than 8 seats !!!!

So beware fitting a snorkel without discussing it with the weasels that take your money every year who may or may not cover you in the event you havnt specified every extra nut, bolt etc on your car.
