The only time (to my knowledge) that I met someone who lives primarily in Australia, she told me Kangaroos are basically like the deer of Australia. Where I live, we call them deer bars (though some call them bull bars, but I think that's mostly just from branding). I've never heard the term roo bar before (other than pie) but I guess her theory checks out.

i never seen a youtube video with so many views and not a single dislike...i watched the whole video and understood why....and i subbed to the channel!
I have a 3rd gen 4runner and was replacing my core support because of damage from a previous owner. I looked at the factory intake tube that sits in the fender well area and it had a fair amount of mud and dirt from my driveway. I also found mud and dirt in my air box. After watching snorkel I stall video with Timmy the tool man, stating the same facts of cleaner cooler air and my discovery of the inside of my air box pushed me to install a snorkel of my own.
Funny this should pop up. I've literally just fitted my custom 4" Snorkle (Raised Air Intake) I made last weekend for my Suburban. I travel plenty of dirt roads here in Oz to certainly make it a worthwhile project. I made it from Stainless even though I painted it. Another great Video, Thanks!!
Australian here. I have a safari snorkel on my Nissan. I haven’t done a water crossing but the high up air intake away from the dirt is handy. Best thing on my Ute! I am posting a video of the walk around at the end of the week if you are interested.
Another great video. I have the breathers and snorkel. I also try to avoid deep deep water, but I did not know about the distributor cap. Going to look up that video. Don’t see it linked. Thank you
I live in the UAE and have just bought a Jeep Wrangler 2 door. My goal is to set it up as an overlander for my wife and I to have adventures here in the desert and Hajjar mountains, love the videos they are really helpful. Thank you
My snorkel is primarily for clean air. 2 times on Death Valley trips my air cleaner got extremely dirty. If you are not leading your going to eat dust, especially if it’s dry and a fairly large group. I leave the ram air cap on when in normal conditions and change out to a pre-cleaner cyclone type when needed.
Might want to check the transmission as well. My vehicle was engineered with no intention of crossing standing water at any level, so that might have something to do with it, but I read in the user manual that the transmission has a breather as well and if the water level rises above it than the transmission will flood with water.
Many causeways are made of concrete and are narrow and you can easily fall off the causeway into deeper water where it’s hard to get out or worse go bobbing downstream. Sometimes the causeway is broken or is missing chunks which are hidden by the water.
I appreciate the recommendation on installing differential breathers and waterproofing the distributor cap prior to installing a Bitchin snorkel. I do not have any of these three things installed on my rig, also an FJ 80, but I intend to in the future before getting to Crazy Offroad. I look forward to a video on waterproofing the distributor cap!
You cover a lot of what I'm going to say. My main priority with my 99 XJ for water crossing was to keep water out of the differentials and transfercase. The vent caps commonly are dirty and don't function properly. The fix I used was to put rubber oil or fuel lines on and run the lines to the highest point in the engine compartment with cheap fuel filters on the ends using zip ties to secure along the way. (If I had a snorkel, the lines could be plumbed into it instead.) There are a lot of other areas that need attention when going through water that most people don't ever consider besides the air intake. Along with knowing where the air enters the engine compartment. My friend had a Nissan pathfinder, and the air intake was just above the top of the bumper (factory)he didn't realize it was located so low but he found out quickly when he sucked water into the engine and bent the pushrods and valves and cracked the crankshaft.
3:56 im studying to be a truckdriver and its probably the same thing with the trucks airdryers so theres no humidity in the airtanks or the whole system.
Great video! I agree with 4xoverland. Dust is the #1 purpose. If you cross water deep enough for a snorkel to matter, you'd better do much more to your vehicle than just the snorkel, as you said. I can't emphasize this enough: You'd also better drain/fill differentials as a precaution, afterward. My advice is to avoid deep water unless there is no other choice. My rings/pinions were destroyed in a 93 Jeep YJ after a water crossing where the axles ingested only about a teaspoon of water. The vents were high enough, but hot axles/bearings get into cold water and they can suck water through the seals, which is what they did. Also, when I was in S. Africa a few years back, I asked several people why they had snorkels on their trucks. Not a single one said anything about water. Every one of them said it was about dust. The bottom line is that unless you do a tremendous amount of work, these things are just not made to go deeper than the factory specifies. Trouble will be on the horizion if you spend much time in deep water. Even once can do the job. Also, take a good look at your factory intake. It may be well engineered enough to be fine on its own, especially with more frequent filter changes. I find a good quality paper air filter to be essential. I keep a spare on trips to highly dusty areas, as well. I enjoy your videos! Keep 'em coming!
Not sure if you realise but safari is a brand name just like TJM snorkels, the Landcruiser on your video is actually a Toyota factory snorkel. Also if you have water anywhere near the top of your wheels without a snorkel you're asking for trouble, the standard airbox intake comes from a baffle inside your wheel arch which means when excessive water is splashing around in your guard there is the possibility of water ingress
Such an awesome video. So informative, so much knowledge in detail and explained in a manner that can be understood by the average person. Keep these videos coming!
I use to have a 90 Series in Venezuela, never installed a snorkel mainly because I didn't wanted to drill the holes. But I did some water crossing and never had an issue with water getting into the engine because the 90 would float, the inside would get filled with water but not the air box. Was I pushing it? Yes. Was I lucky? I believe so. Snorkels give you peace of mind plus they look cool. I bought my wife a Tacoma to use in Houston, TX and although it's a 2wd I'm planning on completely rigging it, specially because Houston is a flood city.
I think you need to differentiate between safari the snorkel brand and a vehicle snorkel in general. Safari makes great quality waterproof snorkels for all the reasons you went over really well, but not all snorkel are the same, especially genuine manufactured ones. Nissan and Toyota genuine ones, like on the troopy shown are not waterproof, not even close, they are solely for dust prevention. Before anyone watches this vid and assumes all snorkels are waterproof and the same will be in for a shock. Otherwise mint vid. Keep it up.
If I could disagree with just one thing. If I go thru a water crossing, and I frequently do, I drive forward not backwards. I drive thru swamps and the level one day may not be the same the next day. So I drive very slowly forward to "test" the level. If I should drop off and my hood goes underwater, and it has several times, I have the chance to back out and not destroy my engine. Thank god my snorkel is as high as it is. I have been scary deep but never deep enough to float. Finally, you can go thru bumper deep or less water and the water splash up and kill the engine. Of course you probably went to fast.... but ship happens.
I seen what happened with his cap in Hollister in the mud pit. Now I'm curious as to how you waterproof a vented part. I'll be keeping an eye out for that video.
those landcruiser's in your video they classed as raised air intakes there not snorkles,they are not sealed and let water and dust in.A snorkle is a sealed unit to keep most of the dust and water out , but they still collect alot of dust so a pre filter on the ram head can stop most of it thanks for the vid
Good video. The tip that's needed is after a day in the sand, take off your air filter housing and vacuum it out. (I've been vacuuming my home air filters for years. Also my wood shop respirator prefilters). Air is 20% oxygen, 80 percent nitrogen. I've always found the most profitable investment, financial, fun, interesting, etc; to be learning and understanding science concepts. There's a method of bringing fresh air into desert buildings. A trough around the base of the building causes the air moving towards and into the structure to drop in air pressure, this releases the load of sand and dust. You can see this in the basin and range terrain between Los Angeles and Las Vegas, in many of the valleys (basins), right in the middle are sand dunes (think of where there are sand dunes in Death Valley). Same process. The moving air is squeezed as it goes over the mountain ridges (range) so even though sand and dust picked up by air moves right over that area where it can 'run into' rocks and scrub and collect most of it carries over. You won't find much deposited sand on a ridge. Are snorkels designed to do this? I haven't seen it. But look at the old round air filter. Small opening, big ring filter. Where do you find a lot of dirt? The filter gets dirty, but the bottom of the filter pan is usually dirty. The design incorporates two benefits. Small opening, so that's all that's needed to supply the engine, but the filter housing is many times larger. First benefit, a larger filter area allows more air through and takes longer to clog up. Second benefit, that large area inside the housing outside the filter? That's your drop in pressure where the heavier dust and wasps gets dropped before the air reaches the filter. Two other useful things to know. The first you're probably well aware of, why water in an engine can destroy it. Liquids, including water does not compress. You can buy a can of compressed air, you'll never find one of compressed water. Water is (I think) also 800 times denser than air. This is why a foot of 10 mph water can knock you down, but your full height in a 60 mph wind doesn't.. The second thing is the basic gas laws. Temperature and pressure affect all gases. Higher temp raises the pressure, lower temp lowers pressure; higher pressure raises temp, lower pressure lowers temp. Avogadro's Law says that all gases at the same temperature and pressure have the same number of particles. So a room full of propane and a room full of air have the same number of 'molecules.' The propane sinks to the ground because it's molecules have so many atoms attached to them. (Carbon monoxide is a lighter molecule than most of the air, so when I see one type of camper that has the CO detector near the floor I'm a bit puzzled). So air and pressure. If you can suck air into your snorkel and then expand it the temperature will drop, the air will be denser, which is great for you engine. However you have to compress the air when it enters the engine. So an expanding snorkel is a waste of time. However, the snorkel is surrounded by moving air. What if the air flowing around the snorkel were used? Small intake in the front, large vent at the back. The snorkel should drop in temp, etc... (Quarantined and being a busy body.) Something else about water, depth and pressure. Snorkels for humans are about a foot, that's it. Deeper than that humans cannot push against the water pressure to breathe. (Scuba diving is about increasing air pressure with depth). What this means to a vehicle is that every additional 12" of depth put a significantly greater water pressure on all the seals. They must be pretty good in the first place if a vehicle an even go four feet deep. And it's probably not new information, but in a stream crossing where you become buoyant and lose traction? Open a door and let some water in.
Beware in the desert ! front wheels can dig (high rpm) sand right in to the snorkel if you same time turn steering from side to side.Put the top head to the rear or use zyklon filterhead.The stock FJ Filterbox have also a "zyklon filtration" and seperate most things in a seperate small box under the main box.
Very simple and clear explanation. We are running our camper with all extended breathers and fully sealed link from snorkel to airbox. We are using a cyclonic prefilter on our snorkel because it's really helping to keep the airbox away from dust and dirt but also keeping it cleaner for a longer period of time. We are thinking that the primary function of a snorkel is more for dust than water. We know it will reduce a bit our air intake in volume and airflow but it's not dramatic. Keep going, love your good content vids and stay safe!
I have one on my 1991 FJ80 land cruiser, yes it's a Safari brand, I faced it backwards because of rain, there is a hole in the bottom the air box so if you are thinking its water tight you better think again, and since air intake is suction not positive pressure, I noticed that my FJ80 ran better, picked a bit of pep I figured its because the stock Toyota picks up its air from underneath, AND the stock inlet is PRETTY DAMN SMALL/RESTRICTED. THEORETICALLY you could cross water nearly 6 ft deep but yse the vehicle "floats. Lots of words to say that yes it's better than not having it.
If your truck's water fording is 30", then you only need to think about extending the air vent if going deeper than the manufacturer water fording? I would suspect taller tires would also raise the fording depth by the difference?
Just to put a finer point on it, cold air is heavier than hot air and stoichiometry is based on weights (14.7 lbs of air to 1 lb of fuel) so putting the same volume of hot air vs cold air, cooler is always better! Great video! Let's fix your axle breather filter!
Have always wanted a snorkel but can't seem to find...other than a do it yourself....for my 2008 Chevy Duramax 4x4 Sportsmobile Van..enjoy the journey...keep the videos coming
I was all ready to talk noise about the other things that are also vented and you went and covered them. I guess all I can bring up is, raise the exhaust exit also if you plan on spending a lot of time crossing deep water.
Maybe you don't need with for example a normal bumper on a hilux. I've replaced my bumper with a rhino evolution, and the same would go for most bumnpers. As you cut part of the innerwheel arch a new hole gets created from the bottom up in the wheel arch, so if you drive in a medium water puddle (just up to the bottom of the bumper) you will actually push it in the wing. I did a ~40cm crossing and had to get multiple cups of water out of my airbox! No engine damage was done and my snorkel is waiting to be mounted!
Hey this is a genuine question. I'm not trying to start a war here. Would an electric truck like the cybertruck take care of all of these issues? I wonder if the battery pack is water-sealed. I'm seriously considering getting one when it comes out vs. getting a ICE truck like a tacoma and then modifying it. It seems like a lot of work to convert an ICE vehicle for off-roading while the cybertruck seems more ready out of the box (supposedly already being made out of steel etc.) but I'm a total novice so what do I know...
I'd love to have one but have concern about; 1. Rust issue on the body panels after drilling holes as I don't see any one on TH-cam doing rust protection and paint job. 2. Rain water / Water from snow getting in. I guess It could be minimized keeping the drain hole on the air box but then having that would it prevent deep water crossings water level above the air box?
Well said! It's MOSTLY about clean air. But, that clean air does come at a small MPG cost. It does take a little extra HP to drag that air down the snorkel. Great water crossing shots. Let me guess; Afton Canyon on the Old Government Road, aka, Mojave Trail? Good times!
Thanks for the video. I have a ‘17 Ram 2500 Cummins with a ramair design AEV snorkel and with the snorkel facing forward it would trip a fault code in my truck. Once I flipped it backwards the code cleared itself and never came back. 🤷🏼♂️
Standard Toyota snorkel option is cold air intake no good for water crossing. The 79 cruisers come standard from factory with cold air intakes, most people will replace them for more air volume and water crossing.
is there any place where we can se in real water being sepatated at snorkel intake... because the velocity of air sucking seems to me that will not differentiate the watter air or other small stuff... maybe something like a myth busters test.
So if I happen to install a snorkel on my Suzuki jimny gen 3 then I'd have to turn backwards the ram every time it rains? Because my air box does not have a tuna can spot hahaha
You talk about the top of your airbox being quite high but it is not about the top of your airbox. On a factory vehicle not fitted with a snorkel, the air intake for your airbox is usually in the fender or engine bay, much lower than your airbox. The water crossing secondary function of a properly fitted snorkel is to raise your airbox intake ABOVE the fender or engine bay intake level.
I disagree a little bit with your explanation of your Air Box Filter, being about the water level. The real problem is Not where (high or low) the filter box is located but where is located the intake TO the air box; as a Toyota user normally those intakes are in the wheel wells some times BELOW the air boxes, so they could be inundated with water even is the water level is not that much high as the driver could see. Other brands may differ in design and location, but the situation could be similar, the standard intakes are NOT designed to restrain water to fill in the air box, because the manufacturers in the Owners Manual tells you the Wading levels of design restrictions (Usually NOT above the middle of the standard wheel). A little note also is that the Snorkel could be useless if you do not plug the drain hole(s) that your air filter box may have. My advise for any Overlander and Off-Roader, from my experience in LatinAmerica from highlands to wetlands... "If you will cross any ford or water body: INSTALL AN SNORKEL" whatsoever the brand. The 2 inches deep stream that you cross going in, could be the 35 inches deep stream that you need to cross to get out few hours later....
So if you have a vehicle with independent suspension like my pajero (montero/shogun) do you need diff breathers? Also do you need a breather for automatics?
I'm in Melbourne Australia and purchased a 2nd hand 1992 1HZ non-turbo 80 series, it came with the Safari snorkel fitted with forward-facing vent. The things I need to do is get diff breathers up to firewall and carry a small tarp for the front of the bullbar for if and when I do a water crossing that needs the bow wave for that high a water level, otherwise, I agree with what you have said. NB none of the 4WD's that I've seen have ever had their vents facing anywhere other than forward, I used to be up north (QLD - Queensland) for a few years and still all forward-facing except for a few of the Round pre-filter units on the Service vehicles that are coming and going from worksites like the mines and the like.
“Safari Snorkel” is the name of the product, proper term, RAISED AIR INTAKE Living in Canada the only time I would turn the top around would be in the winter time, SNOW would cake right at the intake, freezing and restricting air into the engine.
😱.. All of the research Ive done says Clean, dust free air is the primary reason for a Snorkel, and allowing deep water crossings is a bonus. But they arent all created equal and steps need to be taken to make them "Sealed" to better handle water. Dense Air is great! But Im with @Revere Overland, THEY LOOK GREAT! lol..
I just completed the Mojave Road and when crossing the water it came in the doors and got the carpet quite wet. It seemed like I was following the wake, and I didnot have any other problems crossing. Any idea what went wrong? 2018 4Runner
Honestly some vehicles are less water resistant then others. Jeeps also have water ingress issues. Our West Region Director, Bob lined his doors with another strip of weather seal. Seemed to work.
I would add that one should put a 180 degree elbow in their exhaust pipe to prevent water from going into the engine thru the exhaust should you stall during a water crossing
Lol any "power gain" you would get from the cold air a snorkel provides would be negated from the 3 ft of intake your engine now has to breathe through. I'd call it wash if not less HP with a snorkel.
A lot of fabrication shops will be able to make a snorkel that is custom fit to your truck. They look very cool and very custom. You will need to decide if you want aluminum or steel.
😱😱😱😱😱.. Mind blown, just rewatched your "Water Crossing- How to do it the Right Way" and you say they are primarily for Clean Cold Air. Im so confused now! Not really, I just prefer consistency..
I consider deep water wading to be the secondary purpose, and getting the air intake higher off the ground to get the air cleaner and cooler its primary purpose.

Good video. The tip that's needed is after a day in the sand, take off your air filter housing and vacuum it out. (I've been vacuuming my home air filters for years. Also my wood shop respirator prefilters).

The moving air is squeezed as it goes over the mountain ridges (range) so even though sand and dust picked up by air moves right over that area where it can 'run into' rocks and scrub and collect most of it carries over. You won't find much deposited sand on a ridge. Are snorkels designed to do this? I haven't seen it. But look at the old round air filter. Small opening, big ring filter. Where do you find a lot of dirt? The filter gets dirty, but the bottom of the filter pan is usually dirty. The design incorporates two benefits. Small opening, so that's all that's needed to supply the engine, but the filter housing is many times larger. First benefit, a larger filter area allows more air through and takes longer to clog up. Second benefit, that large area inside the housing outside the filter? That's your drop in pressure where the heavier dust and wasps gets dropped before the air reaches the filter.
Two other useful things to know. The first you're probably well aware of, why water in an engine can destroy it. Liquids, including water does not compress. You can buy a can of compressed air, you'll never find one of compressed water. Water is (I think) also 800 times denser than air. This is why a foot of 10 mph water can knock you down, but your full height in a 60 mph wind doesn't..
The second thing is the basic gas laws. Temperature and pressure affect all gases. Higher temp raises the pressure, lower temp lowers pressure; higher pressure raises temp, lower pressure lowers temp. Avogadro's Law says that all gases at the same temperature and pressure have the same number of particles. So a room full of propane and a room full of air have the same number of 'molecules.' The propane sinks to the ground because it's molecules have so many atoms attached to them. (Carbon monoxide is a lighter molecule than most of the air, so when I see one type of camper that has the CO detector near the floor I'm a bit puzzled).
So air and pressure. If you can suck air into your snorkel and then expand it the temperature will drop, the air will be denser, which is great for you engine. However you have to compress the air when it enters the engine. So an expanding snorkel is a waste of time. However, the snorkel is surrounded by moving air. What if the air flowing around the snorkel were used? Small intake in the front, large vent at the back. The snorkel should drop in temp, etc... (Quarantined and being a busy body.)
Something else about water, depth and pressure. Snorkels for humans are about a foot, that's it. Deeper than that humans cannot push against the water pressure to breathe. (Scuba diving is about increasing air pressure with depth). What this means to a vehicle is that every additional 12" of depth put a significantly greater water pressure on all the seals. They must be pretty good in the first place if a vehicle an even go four feet deep.
And it's probably not new information, but in a stream crossing where you become buoyant and lose traction? Open a door and let some water in.
My snorkel on my unimog 404 is on 2.5m! I might register it as a submarine 😄
What a bell you are sir
Beware in the desert ! front wheels can dig (high rpm) sand right in to the snorkel if you same time turn steering from side to side.Put the top head to the rear or use zyklon filterhead.The stock FJ Filterbox have also a "zyklon filtration" and seperate most things in a seperate small box under the main box.
Very simple and clear explanation. We are running our camper with all extended breathers and fully sealed link from snorkel to airbox. We are using a cyclonic prefilter on our snorkel because it's really helping to keep the airbox away from dust and dirt but also keeping it cleaner for a longer period of time. We are thinking that the primary function of a snorkel is more for dust than water. We know it will reduce a bit our air intake in volume and airflow but it's not dramatic. Keep going, love your good content vids and stay safe!
You’re filtering out most of the “decontaminants” 🙄
I have one on my 1991 FJ80 land cruiser, yes it's a Safari brand, I faced it backwards because of rain, there is a hole in the bottom the air box so if you are thinking its water tight you better think again, and since air intake is suction not positive pressure, I noticed that my FJ80 ran better, picked a bit of pep I figured its because the stock Toyota picks up its air from underneath, AND the stock inlet is PRETTY DAMN SMALL/RESTRICTED. THEORETICALLY you could cross water nearly 6 ft deep but yse the vehicle "floats. Lots of words to say that yes it's better than not having it.
If your truck's water fording is 30", then you only need to think about extending the air vent if going deeper than the manufacturer water fording? I would suspect taller tires would also raise the fording depth by the difference?
Just to put a finer point on it, cold air is heavier than hot air and stoichiometry is based on weights (14.7 lbs of air to 1 lb of fuel) so putting the same volume of hot air vs cold air, cooler is always better! Great video! Let's fix your axle breather filter!
Thank you Dan!
Have always wanted a snorkel but can't seem to find...other than a do it yourself....for my 2008 Chevy Duramax 4x4 Sportsmobile Van..enjoy the journey...keep the videos coming
I almost thought this was going to be a Scotty Kilmer video.
Right?! 🤣
I was all ready to talk noise about the other things that are also vented and you went and covered them. I guess all I can bring up is, raise the exhaust exit also if you plan on spending a lot of time crossing deep water.
Love the one take approach! :)
In the the auto repair world we call them green crusty. And they never take a break.
Thanks for the video.
Maybe you don't need with for example a normal bumper on a hilux. I've replaced my bumper with a rhino evolution, and the same would go for most bumnpers.
As you cut part of the innerwheel arch a new hole gets created from the bottom up in the wheel arch, so if you drive in a medium water puddle (just up to the bottom of the bumper) you will actually push it in the wing.
I did a ~40cm crossing and had to get multiple cups of water out of my airbox!
No engine damage was done and my snorkel is waiting to be mounted!
Hey this is a genuine question. I'm not trying to start a war here. Would an electric truck like the cybertruck take care of all of these issues? I wonder if the battery pack is water-sealed. I'm seriously considering getting one when it comes out vs. getting a ICE truck like a tacoma and then modifying it. It seems like a lot of work to convert an ICE vehicle for off-roading while the cybertruck seems more ready out of the box (supposedly already being made out of steel etc.) but I'm a total novice so what do I know...
Hey Mikey, I liked! I liked it! A lot. Another very informative video. Cheers, Mate.
I'd love to have one but have concern about;
1. Rust issue on the body panels after drilling holes as I don't see any one on TH-cam doing rust protection and paint job.
2. Rain water / Water from snow getting in. I guess It could be minimized keeping the drain hole on the air box but then having that would it prevent deep water crossings water level above the air box?
I just watched the diff hose relocation vid. Does the ARB breather have a filter to keep dirt out of the tube or is that even a concern?
Yes it does.
what happens to that cold air in summer the snorkel pipe will heat up making the air heat up?
Id run the top part backwards for clean air and because of rain and bugs.
Well said! It's MOSTLY about clean air. But, that clean air does come at a small MPG cost. It does take a little extra HP to drag that air down the snorkel. Great water crossing shots. Let me guess; Afton Canyon on the Old Government Road, aka, Mojave Trail? Good times!
Good eye! Yes!
Depends on the application. All current snorkels (newer vehicle models) are dyno and flow tested to ensure the engine is not losing any power.
Thanks for the video. I have a ‘17 Ram 2500 Cummins with a ramair design AEV snorkel and with the snorkel facing forward it would trip a fault code in my truck. Once I flipped it backwards the code cleared itself and never came back. 🤷🏼♂️
I've got the same truck and have been looking at adding a snorkel. Thanks for the info!
Thank you for helping me decide what to do with my Troopy snorkel… I’ll get the under bonnet things done first. 🌸
Standard Toyota snorkel option is cold air intake no good for water crossing. The 79 cruisers come standard from factory with cold air intakes, most people will replace them for more air volume and water crossing.
A snorkel won't raise the level of your alternator or ECU on more modern vehicles.
Great info. I thought this would makes it easier to go in water. But need other stuff as well. Thanks
You bring in more Cleaner and colder air into the intake
With a more custom design, there should be a way to get the top of the snorkel inside the limb riser.

is father's day new years eve 2023 ; not MY bitchinderella | CORRECT
Good video! Keep them coming guys!
is there any place where we can se in real water being sepatated at snorkel intake... because the velocity of air sucking seems to me that will not differentiate the watter air or other small stuff... maybe something like a myth busters test.
So if I happen to install a snorkel on my Suzuki jimny gen 3 then I'd have to turn backwards the ram every time it rains? Because my air box does not have a tuna can spot hahaha
You talk about the top of your airbox being quite high but it is not about the top of your airbox. On a factory vehicle not fitted with a snorkel, the air intake for your airbox is usually in the fender or engine bay, much lower than your airbox. The water crossing secondary function of a properly fitted snorkel is to raise your airbox intake ABOVE the fender or engine bay intake level.
Informative video bro. Now i know i need first the differential breather to put in my Hilux 4x4. From Philippines.
I disagree a little bit with your explanation of your Air Box Filter, being about the water level. The real problem is Not where (high or low) the filter box is located but where is located the intake TO the air box; as a Toyota user normally those intakes are in the wheel wells some times BELOW the air boxes, so they could be inundated with water even is the water level is not that much high as the driver could see. Other brands may differ in design and location, but the situation could be similar, the standard intakes are NOT designed to restrain water to fill in the air box, because the manufacturers in the Owners Manual tells you the Wading levels of design restrictions (Usually NOT above the middle of the standard wheel).
A little note also is that the Snorkel could be useless if you do not plug the drain hole(s) that your air filter box may have.
My advise for any Overlander and Off-Roader, from my experience in LatinAmerica from highlands to wetlands... "If you will cross any ford or water body: INSTALL AN SNORKEL" whatsoever the brand. The 2 inches deep stream that you cross going in, could be the 35 inches deep stream that you need to cross to get out few hours later....
#1 question I get, "do you drive under water" durp durp.. I had a kid at a drive-thru ask "is that your exhaust " lol
How bout a video about how you made and how you atrach your brush wires from your bumper to your roof rack.
HE already did.
Fkng outstanding breakdown!👍👍👍👍
So if you have a vehicle with independent suspension like my pajero (montero/shogun) do you need diff breathers? Also do you need a breather for automatics?
I'm in Melbourne Australia and purchased a 2nd hand 1992 1HZ non-turbo 80 series, it came with the Safari snorkel fitted with forward-facing vent. The things I need to do is get diff breathers up to firewall and carry a small tarp for the front of the bullbar for if and when I do a water crossing that needs the bow wave for that high a water level, otherwise, I agree with what you have said. NB none of the 4WD's that I've seen have ever had their vents facing anywhere other than forward, I used to be up north (QLD - Queensland) for a few years and still all forward-facing except for a few of the Round pre-filter units on the Service vehicles that are coming and going from worksites like the mines and the like.
Pretty much every custom stainless steel snorkel faces backwards
@@Hazardbone Ok thanks, I've not seen any in my area as yet.
“Safari Snorkel” is the name of the product, proper term, RAISED AIR INTAKE
Living in Canada the only time I would turn the top around would be in the winter time, SNOW would cake right at the intake, freezing and restricting air into the engine.
😱.. All of the research Ive done says Clean, dust free air is the primary reason for a Snorkel, and allowing deep water crossings is a bonus. But they arent all created equal and steps need to be taken to make them "Sealed" to better handle water. Dense Air is great! But Im with @Revere Overland, THEY LOOK GREAT! lol..
Wouldn't driving into heavy rain cause water intrusion?
Do you have any suggestions for keeping water out of door jams
Some try a second bead of weather strip.
@@OverlandBound also what is your take on steering stabilizers?
very nice i like off road.
where can I buy a 80 series air filter
80 series dizzy cap mod please! ive been brainstorming this one a while
Where’s the last two videos (Thursday-Friday)!? Are you guys okay? Have you officially gone over landing off the grid?
Snuck that Friday chat in at the last minute. 😏 We’ll have something new later today!
I just completed the Mojave Road and when crossing the water it came in the doors and got the carpet quite wet. It seemed like I was following the wake, and I didnot have any other problems crossing. Any idea what went wrong? 2018 4Runner
Honestly some vehicles are less water resistant then others. Jeeps also have water ingress issues. Our West Region Director, Bob lined his doors with another strip of weather seal. Seemed to work.
@@OverlandBound Thanks for the response. It was my big first water crossing and "everyone" on TH-cam seemed to cross it without issues.
@@OverlandBound you're not wrong on that lol, wear swimming trunks if you plan on doing any water crossings in a jeep.
Put the vents on recirculating
I thought the ram effect only happens at very high speeds?
Anything above 30km per hour is noticeably on mine.
I would add that one should put a 180 degree elbow in their exhaust pipe to prevent water from going into the engine thru the exhaust should you stall during a water crossing
Great video. Long story short, more power, cleaner air and air filter, better fuel efficiency and water crossings. Why on earth wouldn't you get one!
Good video .Learned something new
Great video brother
Thank goodness I live in the desert.
Great video, thank you!!! But you forgot another important purpose of snorkels: They just look cool. :)
I don't think the purpose of nitrous oxide is to cool the intake charge. It is an oxidizer.
Lol any "power gain" you would get from the cold air a snorkel provides would be negated from the 3 ft of intake your engine now has to breathe through. I'd call it wash if not less HP with a snorkel.
Gimme a snorkle till the coows come home and they kinn help with the diff breather ...😁pip pips and carryon
I need to find one that works with a F-150
From what I've seen there are none for it specifically but I did see one guy modify a Jeep xj snorkel to fit on an 09-14 f150 I believe.
A lot of fabrication shops will be able to make a snorkel that is custom fit to your truck. They look very cool and very custom. You will need to decide if you want aluminum or steel.
Solid information thanks
You need a snorkel even with the fan just spinning is enough to throw water up which goes straight into the air intake which is sucking
Australia... Wooooo 👍🏻👍🏻👍🏻🇦🇺🇦🇺🇦🇺🇦🇺
I think a video about the distributor would be help full
Great explanation
Stay focus and get to the point!
Why not face the air scoop to the rear of the vehicle
😱😱😱😱😱.. Mind blown, just rewatched your "Water Crossing- How to do it the Right Way" and you say they are primarily for Clean Cold Air. Im so confused now! Not really, I just prefer consistency..
Haha thanks for the video and you got video bombed at the end
