Prior to the T4 I had a 200TDi Land Rover...and I had it fitted with a snorkel - open throat, no dust pod. Mainly because I was young and inexperienced.The circular piece on the end is normally a sand filter for dusty conditions, I would probably just fit an open mouth piece ala Landrover

It made precisely no difference to the performance of the engine as a cold air intake. Dust wise it did make a tiny difference to the typical lifespan of a filter...but not enough to justify the expense. When you were in convoy...the snorkel actually increased dust consumption because of the dust suspended in the air.
It also caught every overhanging or trailside branch...
In my opinion, a snorkel on a T4 is as valid a proposition as a skiing elephant.
Probably...though how anyone can see a visual benefit in what appears to be a stormwater downpipe, bolted to the side of shed that's still waiting for guttering, is a minor mystery to me...I imagine we are talking more about dressing the Syncro with a snorkel for visual benefits over actual performance benefits?
thats just a dust cover to the flywheel. I cant recall seeing a breather on the T4 gearbox, but it may have one elsewhere that i didnt see? However the rear diff does indeed have one and would need to be extended, which I have done already as I was down there fitting it.if your going that deep you need vent pipes on evrything that could be open to water ingress the gear box has a silly little rubber bung which in a lot of cases is missing so water will go strait in its just not worth it and not designed for it plus you have to cut a hole in your wing
We've taken our T4 out into those very environments...frequently. Heck we used to live there! And we've just come back from the Flinders Ranges again. The dust issue is over-rated. Yes you do need to make a little extra effort to mitigate it (like be prepared to bash the filter out occasionally!) but you don't need to be over the top.Seano, you have some valid points, and I know your against it.., but for me im thinking about the environment as well. I've brought my banger down under and see the graded tracks (which im heading out into over WA and NT) as more of a dust haven, and after a new engine/rebuild that is one big reason for a snorkel with cylone filter, especially when im in convoy and alot of dust in the area around my air in take. Actually VW specifies a heavier duty air filter, both panel and round for hi dust environments, there's a specific part number for it.
Overall I am weary though and not 100% convinced,,,it may make me push the van further than it can handle, as really, the T4 syncro isnt as good as the T3 syncro or other 4x4's,,,,and a water crossing deeper than the standard air intake poses questions regarding seals. I've replaced some, but to get the inside of my campervan so wet, well, it would destroy my interior and my home :*
