I bet it depends on the type of snorkel and how its fitted.

Ive only ever had safari and ive never been disappointed. On the V8 it was plummed direct (continuous tube) to the air box. Its a similar set up on the discovery, with the ducting taking it into the airbox and blanking the feed and on the tdci, i spent a lot of time sealing the pipe and the wing to snorkel joint.

WIth safari you then get the ram air affect - with air taken higher than the normal air flow so cooler and cleaner.

Its probably different with the genuine one Mike

I fitted one of the "cheapy" types (I think it was from Craddocks) and it has been fine. It's a bit of plastic at the end of the day and is pretty much the same as my mates Safari one, even if the quality isn't quite as good.

The only thing I would say is that it was a bit of a sod to fit. I've since taken it off my old Td5 and when I get chance I will fit it to my 110.

Actually, there are substantial differences between Safari, and cheap alternative snorkels. Firstly, most copies don't seal in the easy way, with a pipe going through the wing...many rely on sealing around the outer wing vent - which as we all know just isn't going to happen, no matter how much silicone you use.

And if you ever roll your vehicle onto the side of the snorkel, a replica will simply shatter into many bits, and cause damage to the vehicle...people have found out the hard way, using both, and a Safari snorkel is made from far stronger material, that stays intact, and actually helps protect the rest of the body from the impact. 1998 110 300Tdi White Hard Top

The sealing issue I might possibly agree with but from what i've seen there's not alot of difference. Elsewhere on this forum I think there is a reference to the genuine Land Rover snorkel that has a hole in the bottom of it!

On the Td5 the sealing issue is a bit mute anyway as the ECU is under that seat and is lower than the level of the bottom of the raised air intake. I don't know what everyone elses is like but mine doesn't look particularly watertight.

I don't agree with the snorkel acting as body protection tho..........

The genuine land rover raised air intake is not a snorkel - its a raised air intake, there is a difference between a sealed snorkel system and an RAI Thumbs Up .

Safari Snorkels are designed to allow full and prolonged submersion.

The quality of safari snorkels in every respect is well worth the extra - cheap copies are just that and must use cheaper parts to keep their profits high. Mike

Just my experience, yours is obviously different. However i'll stick to roll cages for protection thank you!

Laughing Laughing A better idea! I wasn't trying to suggest a snorkel is a safety or anti-rolling device, just differentiating the way some react if rolled onto! Wink 1998 110 300Tdi White Hard Top

I agree with Mal's views myself. The BAS findings don't put me off as there are other benefits that outweigh the so called issues they cause. There is colder and cleaner air for a start and a cooler intake temp IMO is nothing but a good thing.


As to aesthetics, I fully agree. Certain RAIs like in Mal's picture enhance the Defender look. Thumbs Up

As to the argument of colder and cleaner air, I have to scratch my head. Why would air taken in at just one meter higher than the standard side mounted air intake of the Defender be any colder or any cleaner at all? Maybe it makes a little bit of sense when driving in a convoy in the desert (dust and radiation wise), but here in Europe? Doubt that there is any difference at all.

Now scientifically...... Rolling Eyes , it is true that air temp decreases as you go higher up in the atmosphere.
Let's look at it from a physics view point.....Between sea level and 11km of altitude, air temp will decrease in a steady slope at a rate of 6.5°C per km. So 15°C at sea level means -56.5°C at 11km altitude.
So this essentially means that air temp at the RAI intake which essentially is "a bit more" than 1m higher than the standard air intake, would be "a bit more" than 0.0065°C lower there. Shocked Thumbs Up You never actually own a Defender. You merely look after it for the next generation.

If you employ the air is colder argument then I think you should also be acknowledging the fact that the air is less dense at the top of the intake - thereby offsetting some of the gains Whistle

KF9 - I'm liking your mod - I wonder why the OEMs don't go for that solution from the beginning? Far better to not have to drill windscreen surround and thereby compromise it. Assume it's a Sikaflex type sealant you have used?

but that really is the point of a snorkel isn't it?

Having said that I had a an official LR/Mantec snorkel fitted to a 300TDi and nobody mentioned that the airbox itself had a drain hole in the bottom and that the rubber mounting lugs were just grommeted in to the underside!

Cold air is more dense than warm air - air density decreases with height at a defined rate, the airflow and engine heat also impact the air intake at the normal level.

On the Safari snorkels their instructions tell you about the points to seal on the 300 and like the TDci they show the points you need to seal to make it water tight.

The land rover/mantec job is a RAI not a snorkel Mike

If you buy a Safari snorkel for a TD5 its the same model as for the Puma, its only a raised air intake not a snorkel. Your relying totally on the seal between the fitting and the wing AND the OEM inner fitting between wing and air box. To get a proper snorkel for a TD5 use the 300TDI Safari Snorkel which fits correctly and does not rely on the seal to wing It uses a hose between snorkel and airbox. As you might guess I've been down this route when fitting one to my TD5 this year. 2007 TD5 90 Hard Top

Correct, cold air is more dense.

But at altitude, the oxygen density is decreased (altitude sickness?)

I noticed a few weeks ago that my Safari snorkel bracket finish was beginning to look tired. Manufactured a 3mm thick stainless bracket 150mm long with internal measurement of 45mm with a fold at the 20mm point.

Old bracket.

Removed the bracket and was surprised how rusty the captive threads were. The rust had migrated considerably on the rear of the old bracket under the powdercoating and most of it was 'bubbled.' No rust on the bolts though.

Cleaned the whole area off and degreased. With a liberal bed of my old favourite sealant (name available on request) I adhered the new bracket to the pillar and cleaned the excess sealant off.

I done a similar modification on my Mantec Snorkel though used a 4mm piece of Ali Working towards Carry on camping!
