Hi group,

I am planning on installing a snorkel/raised air intake on my 200tdi
Defender to allow me to wade deeper when on green lane weekends. The
main decision point seems to surround mushroom top or straight top. I
am concerned about what the effect would be when driving in heavy rain,
and worry that the straight top, when pointing forward, may take in too
much water and damage the engine. I realise that you can turn it
around, but don't want to be getting out and turning it all the time.
If I leave it pointing permanently backwards, will the engine be losing
power because it is not getting a ram air type effect? Or am I just
worrying too much?

My actual requirements are :-
- Snorkel is primarily for occasional wading only (plus wading kit)
- Must be easy to fit, preferably no drilling holes in the wing,
unless there is a very good reason to do so, such as a better seal.

Can anybody provide me with snorkel recommendations please?

Many thanks,

Dave.

 
Dave Hi,

There are several options.

More widely known ones are

1. Mantec plastic type snorkel with mushroom type air intake. Mantec also
makes a full metallic version (which was the first one to be produced for LR
vehicles AFAIK). The new plastic one is a bit cheaper but VERY well made.

2. Safari Snorkel. This is the second most widely known type of snorkel for
LR vehicles. It is different from the Mantec in both the design of the body
(somewhat box like compared to the tube type of Mantec and other makers of
snorkels) and the air intake (which looks like a scoop and can be directed
both at the front (for air ramming effect) or at the rear (when it is
raining or you wish to avoid getting too much dust to the air filter)

3. Other newer makers such as Rebel4X4, firstoffroad etc. Most of them
make tube like snorkels from steel or even stainless steel.

--------------------

I tend to like the Mantec ones more. To be frank with you both my vehicles
(Discos 200Tdi) came from the factory with Mantec snorkels (both being
genuine Camel Trophy evented vehicles) so I got to know Mantec first. One
more thing to consider about snorkels in general is that your engine will be
breathing fresher, cooler and cleaner air since it will be receiving its air
supply from a higher position when compared to the standard air intake of
the Defender (either on the wing top or the wing side). This will give you a
slight performance advantage and for sure a longer life span for your air
filter's element.

Take care and Happy New Year.

I run both types on my 90's

I never have a problem with heavy rain with the safari guard.

Although once I was driving through a gully and managed to dig the top
of the snorkel into the ground which instantly filled the air filter
with sand !!

So now I run with the top pointing to wards the other side of the car
when off road.

My vote goes for the safari guard purely on cosmetic grounds.

I prefer the el cheapo piece of canvas tucked under the bonnet and
down over the front of the vehicle to keep the water out of the engine
bay. I've "waded" a SIIA using this method for years and my only
mishap is when I forget to close the under screen vents and cop a
lap full of luke warm slime - or my wife does which is far worse.

Snorkels seem to encourage a vehicle owner to try deeper and deeper
water crossings until one day the vehicle floats (for a short time)
and needs a full on recovery.

That's why you have to open the downstream door
