Update: i looked at Donaldson's website, the company for the prefilters. they have one that has been taken to 70 MPH with no probs and its a bowl-less design, so i shouldn't lose any airflow.

What's the Donaldson P/N for that? Link?

its the topspin filters. i think i the article i saw was in taco magazine. it was a race-truck that had the Donaldson topspin and was flying around at 70+

Heres the link https://dynamic.donaldson.com/webc/W...?section=10105

So if you have a snorkel (specifically the Airflow) and you are driving normally through snow/heavy rain, are you supposed to turn the hood around? Should you then not drive above 15 mph like Airflow states?

I'm new to anything about snorkels, so just trying to learn more.

It has a water separator in the hood so water shouldn't get through to the intake. I think you only turn it around on trails below 15 mph so it don't get snagged on anything? Someone will clarify.

i had issues with water getting into my intake during a big snow storm coming over some passes...real heavy wet snow...it built up in my hood and began coming into the intake...soaked through my filter and soaked my MAF sensor fucking with my truck enough to where i had to pull over, take my intake all apart and let everything dry

it could be the design of the airflow hood versus the safari? or it could be that in that situation even the safari design would have had issues...i don't know

the airflow has a significantly larger opening and the sarafi design also angles down in the front that could help in snow/rain conditions to limit the amount of water from even hitting the inside of the hood

both designs have water channels in the sides of the hoods that in normal rain/snow conditions, will allow the water to escape the hood, outside of the intake tube, preventing water from getting in the intake..

a pre-filter is a way to ensure NO water will get in under heavy rain/snow conditions and greatly improves the filtration of dust before hitting your engine filter

An added benefit of the unique Safari Charge Air Ram is that it can be rotated to any position. This means great peace of mind for those who plan to travel in cold or high altitude conditions where heavy snow falls are anticipated. By rotating the air ram to face away from the prevailing wind/direction of motion, the air ram delivers additional protection from the choking effects of snow build-up inside the air intake.

The Air Ram
Air entering the Air Ram swirls violently, creating a cyclonic effect. The heaviest particles are ejected by the centrifugal force to the periphery of the swirl. There, they hit the vertical ribs where air pressure takes over to eject them out of the four slots at the base of the Air Ram. At this point, the air pressure pushes them out. The finer particles that are not ejected are removed by the vehicle air filter.
Comparison: not all Air Rams are equal in performance.
It is preferable for the Air Ram to have an open face without a screen because the screen deflects the airflow. The surface ratio of the open face to outlet aperture must be a minimum of 1.4:1. If the ratio is lesser, it will be insufficient to create the cyclone action that separates heavy contaminants effectively. Approximately 30% of the incoming airflow (above 25kph / 15mph) is used in the separation process. At Airflow, we ensure that the Airflow range uses a minimum of 1.4:1 for the 3” air ram, 1.7:1 for the 3.5” air ram and 2:1 for the cold air induction air ram. Any deflection of the incoming airflow must be avoided since it dramatically affects efficiency.
Deflections may be caused by:
1-Air Ram situated in close proximity to the bonnet/hood of the vehicle,
2- Air Ram with a curved or foiled roof,
3- Turning Air Ram away from travel direction,
4-Where Air Ram design makes the air go back on itself at an angle greater than 100 degrees.
If the Air Ram is turned away from the direction of travel, it will lessen the necessary positive pressure. In extreme situations, at higher speed, a vacuum may be generated causing irreversible engine damage! Incorrect Air Ram design may cause excessive induction noise, lack of separation and air blocking by vortex at various speeds. This air blocking will limit airflow. This is a common occurrence when “looks” take priority over functionality. If the Air Ram is moulded on the body of the snorkel (for aesthetic reasons) it does not provide particle separation, thus all contaminants need to be removed by the internal air filter. This increases the maintenance cycle of the air cleaner. Furthermore, this configuration may cause a vacuum into the snorkel, thus increasing the risk of engine damage.

For all the Airflow people out there...have yall had any issues with heavy rain storms and water getting to the airfilter? Down in the south we get some pretty nasty thunderstorms and hurricanes and dont want to mess anything up.

Safari fits like ass. Airflow fits perfect. Safari offers lots of restriction. Airflow is huge and smooth. What else is there?

I've driven through some SERIOUS snow and rain storms. And haven't had any issues with water getting in yet.

So..... How much does the Airflow stick up above the roof line????? IE Top of the roof to top of the snorkle intake.

Since Mike already bumped this one, may as well tell anyone looking that I'm now a dealer for airflow, so if anyone's interested, PM me.

Went and measured mine and its about 5" above. There is room to hack off about 1" of tube to bring it down some if you'd like it a bit lower.

Is that from the edge of the roof straight across to where it intersects with the line of the snorkel? Or is that to the highest point of the roof.

Highest point of the roof. I didn't break out a straight line to get an exact measure but its close.
