Just look at the pics. I did a kind of experiment where at the end I filled the hollow bottom and sides giving a more "gentle" shape so the air passed through more freely. So at the end I got more air (or at least faster).

However, if all this made any big difference in performance?.....

Something to consider is the volume of air sucked by the engine and how much air passes through the RAI at any speed.

That's the one.... but £30!

When selecting a snorkel it all comes down to necessity and then afterwards preference

For example:

I needed a snorkel which allowed the following:

- Deep wading.
- Fit with a roll cage.
- Hot/ dusty climates.

So straight away I couldn't go for a rigid snorkel without cutting out the wing etc. I then found out that Mantec do a flexi snorkel which has clamps that fit a SD roll cage..... Winner.

I had read the reviews about MANTEC being RAIs and not snorkels...... so I would then have to modify it to be fully sealed- How wrong was I!! The instructions showed in detail how to seal up the puma intake system and the kit also included a syringe of sealant.

Then the last thing I needed to do was equip it for hot/ dust climates. So an ARB top hat pre-filter was in order.

So, as a result I have covered all my bases when it comes to 'necessity'. Due to this I had pretty much no choice to 'Preference' but the system looks and sounds awesome so also happy with that.

The result:

So..... If you don't have a cage there are loads to choose from. Then it becomes preference. Do you prefer the flexi type or the rigid? Do you want a cone, scoop, trilby or pre-filter on the top?

Surely the Safari type's would add a slight "Ram" affect to the air when in motion in affect helping and slightly forcing air into the air intake system? Can't see how the Mantec version would have quite so much effects.

I am sure you have heard that (as may others have told me).... but to be blunt... What a load of CR@P.

A. For this to be effective you would have to travel at about 150mph.
B. Diesels don't have 'vacuum'. Therefore you can force as much air into the intake as you want but the turbo will only allow a certain amount past (which is the right air-fuel ratio).


Everyone is happy with 'their' intake......... They wouldn't have it otherwise

Just another point before i make my decision how does a snorkel effect the vision from the screen. I like the view at the minute with the very slim pillars etc, anyone got any pis looking from the inside looking out thanks Jay

You won't be wanting to put a Brownchurch HD roofrack on then I've one and the support bars to the bulkhead window brackets overshadow the snorkel

I can't see either the cage or snorkel at all. Will take a pic later.

Bloody hell. What a load of pony talked about snorkels. Look, the ford engine is hardly in a state of high tune. You could bolt piece of drainpipe on and as long as you seal it it would be fine.

Well said Mike I was also waiting for the "you don't need one" sentence

I have seen what happens when you take a defender into deep water without a RAI and it's wallet twitching stuff, turbos, engines blah blah blah so there is a need in certain circumstances for them.

The diesel turbo engines positively suck the air in through whatever aperture is fitted, so all this talk about ram air - I'm not convinced

Final point - once you have drilled the wing and windscreen pillar there's no turning back.
