Raised Air Intake

Well, I think the Landrover Raised Air Intake is quite cleverly designed. It is not a snorkel as there is a gap between the raised plastic extension and the original air intake tube in the rear of the panel. This is for any heavy objects and, I suspect, water from tropical downpours to escape before being sucked into the filter. I would expect it to be most efficient in the conditions you describe.
When I get some time, I'm going to see if there is a way to readily convert the gap into a sealed unit, so that it would act as a snorkel on the rare occasions when you'd need one. I'm thinking of a connecting box with a sliding floor that can be closed for snorkel or opened for normal use.

If you like the look, then buy one ... but IMO it won't make a difference to your air filter.

Don’t blow out the filter - it damages the membrane and makes things worse.

Just tap it out.

Suck, not blow. [emoji16]

On my D4 I have the Airflow snorkel. Looks like a Safari but a lot cheaper to buy. The head has slits it where it goes over the pipe on the"A" pillar. This is designed to let water escape that gets forced in when driving along. Also Airflow sell a fine filter sock that you can purchase to put over the head. This acts as a pre filter. I have only used it when I go on club trips where I am not the leader. At the end of the day it is quite dirty, so it does work.

"Suck, not blow" Not sure I'd agree with you there as when I worked on plenty of mine sites if we didn't change the filter every shift we used to blow some equipment's filters from the inside out if they weren't operating in very heavy dust areas.
Those machines working where the dust was like talcum powder got filters changed at least twice a day. Changed many filters every day and over a week there would be hundreds got sent to Perth for "washing" which I was told got done by a machine which gently blew them and sucked them out.

Told one operator to stop using the service trucks air to blow his aircon filter out on one rough road job I worked on but he continued to ham-fistedly do it until he wrecked it and got very upset when the mob I worked for wouldn't replace it. Not so much OHS around in those days.

Plus I sacked a mobile "mechanic" who used to service my Prado when I caught him blowing it from all directions...inside out and out side in! I also caught him using 5 different types of oil in my engine but that's another story.

When we're on the road I always take a spare air filter and change when necessary and clean or replace when home with a new one.

Even with no other cars you will still get dust drawn in from the stock fender intake

On a D4 I would beg to differ.

I’ve done thousands of dusty kilometres on my D4 without a snorkel and the intakes location on the DS is essentially dust free.

Unlike the earlier units where it drew from internally in the guard, the D4 doesn’t have a cloud hanging around its intake.

I since fitted a snorkel and there is no change in filter impact.

Yeah the more i look into it and my RRSMY10 (as its meant to be closer to d4 than d3), they have two parts ? lr013711 and phd000714 which pipe the air, though phd000714 has holes, i plan to fill them.

Very interested to hear your account of lack of difference in dust levels b4/after.

How did D3 connect airbox to fender grill ?

D3 intake tube is plastic with a textile like membrane , not water tight but wouldn't suck in dust.

I think the d4 one is soft fabric membrane like too, as thats what it says the part is for (d4) and whats on my rrs
