Moving Air intake

Bostokkelos · Mon Feb 14, 2011 11:22 am

Ok so I dont want to fit a snorkel, But the air intake is (according to me) very exposed sitting so far to the front.
Isnt there something else I can do (like moving it) and how to protect my car. If I do move it, would it have an effect on the car?

tokkelos,

Please define "exposed". Not sure if a re-position will make much difference when you drop the nose under water.

Dust is not a problem, I have on occasion experienced unbelieveable dust and the next morning when I want to at least tap the old aircleaner on the floor to shake the worst out, it is still clean.

I believe that more than a decade of rule on the Dakar desert will have tought the Pajero guys a few things about air intake design.

Keep a bow wave and you will be fine

I have the same concerns with my Gen 4, but have done water crossings and havent had a problem, yet....

I was once told the best would be to tape a plastic bag or towel over the bonnet onto the grill to prevent a surge of water entering, but havent had the need, yet

Dust is not a problem, the flter will do its job. Ita water that bothers me.

I do not believe there is a viable alternative placement of the air intake box to prevent water intake.

One suggestion is to place a air tight blanket over the grille when crossing water - that way creating an air pocket behind the grille in the engine bay. Obviously the bow /wave is important to "push" the water away steadily.

If you plan to do water crossings that are this deep, you should really consider a snorkel and breathers on your diffs and gearbox.

You will be fine as long as you remember this is not a submarine

Take if from me.
i was horrified when the nose took a dip into the muddy abyss on my first outing but was glad to see not much went into the air intake. just kept the momentum going and got out the other side.

If you look closely you will find that the intake actually pulls air in from the higher part of the engine bay on the gen3 (provided the rubber seal is still on the bonnet.

That rubber seal prohibits any water coming in from between the grill and radiator. It is IMHO a very inefficient design as you are getting hot air in to the intake from funny angles as well.

I have removed the piece of rubber there to allow cool air to come in between the grill and radiator and I'm sure I'm getting better performance. I cleaned the intercooler at the same time (was hardly any oil in it at all) and my economy bettered by about 1l/100km since doing those 2 things.

NB: I'm not worried about water ingestion as I'm very scared of water and stay far away from big puddles like that.
