Cyclone Pre-cleaner/dust separator

[Crozhawk]

This looks awesome! It seems like I have to change my damn air filter every oil change or more. A buddy of mine is getting one on his 07' FJ and were going to retrofit to see if it's possible to fit it to the V8. They will be offered as an option for the 08' FJ offroad package. Were gonna have to look at diameter, ACFM of air flow and the other specifics to see if it's viable. I'll keep you posted.

Apparently tHey are already on the Prado's. We use the same basic concept/theory on our helicopter turbine intakes and they work very well.

Also, they are not compatable with CAI but are compatable with a safari snorkel.

They list for $113 but our local group is getting them for $93. With enough interest, maybe we can get a group buy or something.

Guys with V6 4Runner should be able to fit it, however with the location of the V8 airbox I seriously doubt you will be able to fit it. I wish we could get a snorkel for the 4RUnner though.

Would this be a direct "bolt-in" for a V6 4Runner?
Does it come with the necessary brackets, for $93?

just get it and slap it in there, it's just hose clamps:spank: it's cool that toyota revived this design, it's similar to the 80 series Land cruiser. there is a 'tuna can' that holds the heavy dirt, you empty it out.

[Crozhawk]

the way i'm looking at it, for a V8, there may be a way to modify it to sit in the lower part of the airbox and cut a hole for the dust discharge on the bottom. As soon as I can get my hands on one, I should be able to tell whether or not it will work.

Let us know if you can get it to work. Would be an interesting mod.

croz,
you need the whole assembly w/ the fan, not just the discharge port. the cyclonic action spins and traps the dirt around the 'cleaner hose' and slips into the discharge slot from there.

the V8 airbox is a different design and has no cyclonic action. You would need a drum-type airbox to create the swirl movement to 'pre-clean' the dirt before it goes thru the filter.

you might still be able to mount it on the V8 inside the fenderwell, hidden from view but I'm not sure if there is room...

Having the v6 I would be interested in a group buy for this. Please keep us posted.

Thanks.

i was thinking of modifying the whole box, after a 2nd look, it doesn't look like the whole assembly will fit inside, although it's close.

The filter box shape does not matter, the cyclonic separation happens prior to entering the filter box (in the case of the V8, it would be inside the filterbox but it still happens inside the assembly prior to the air exiting into the box).

Without it in hand, it looks like you would have to cut the entire box, ...which might be a little risky of ruining it if you didn't cut just right. Then the factor of sealing the seams and what not. I like your idea of the fender well, ....maybe possible with some additional tubing?

[Mikestang]

Neat idea, but I would think that putting anything inside the intake tract would result in a decrease in engine performance. A before and after dyno test would be nice to see.

[Crozhawk]

agreed ....especially dirt

I don't believe it would be an issue for the V6 as it was designed for that application. It is now stock on the FJC and was on the Prado from day one, and no change in rating from Toyota for the V6 with it in.

This type of system has been used in many applications, and if properly designed will yield the best filtration and performance. In the case here it is just used as a prefilter to get some of the biggest particles out.

Now messing with the V8 intake tract to fit it might result in a very different story.

Why not just design a snorkle, either under hood or external, and leverage this to feed air to the stock airbox?

[bulldog]

A snorkel would help, but for real dusty conditions this is a very useful feature as it removes some of the dirt before it hits the air filter. It is used in conjunction with a snorkel in other parts fo the world.

Older 4WD trucks used to have somethign similar build in, I beleive even the 100 still has the old barrel filter design to help prefilter dust and sand out before the air hits the filter. True that a lot fo the older filters didn't have the advanced material and filterign capability of modern filters like the ones in the 4RUnner. However my air filter seems ot be shot after only a few offroad trips in dusty conditions. It would be nice to have something that can extend the life of the filter.

The theory behind a snorkel and dust/dirt is that it takes air from much higher up. SO the dust content should be lower. It actually helps a bit if you drive in a convoy, but plenty of dust still gets in.

WOuld be interesting to see the report from folks using these and comparing their filters to non fitted units after driving in the same conditions.

[Crozhawk]

I'm waiting for my buddy to show up with his and I'll see Yoda's the week after next. A possibility for V8 owners might be fitting the V6 air box or maybe modifying a CAI or something.

I really want to try to make this work but some other things have my attention right now.

[Teotwaki]

I am interested. Average air filter cost is $20 so the upgrade could pay for itself quickly.

[Crozhawk]

If i had a V6, that thing would all ready be on there!:guns:

You missunderstood me. I meant that we could build a snorkle, and in its design INCLUDE this as part of it. :)

Yep i think it would be a waise move for folks that drive lots of dirt road.

Yep me too.

Oh sorry, and yes very good point. Now we just need to find a way of producing said snorkel :D

[Mikestang]

Look at that picture, that's one big plug in your intake tract. I have a feeling it's going to kill performance. Where the air previously had a clear cross section to flow through it now has to make its way through some little slots.

Dunno, the power ratign didn't change. The slots you see in the pic is only the ends of the vanes that is used to cause the centrifugal force, the slots are much wide as it is a vaned setup like in a turbine. I'm willing to bet the openeing surface area in the vanes is uite a bit more than the narrowest point in the intake tract.

oooooh..........I like! Who's getting one first?!

[Teotwaki]

If it saves filters (at $20 a pop) then it might pay for itself in a decent amount of time.

[AlexJet]

Any news on this?

[Crozhawk]

My buddy put one on his FJ and it appears to be working nicely. If I had a V6 I'd definitely do it.

What is the lowest price for it? Can someone make a deal?

PM Flyndrive (Ben). He may be able to help you out, not certain though, the discount may only be available for the local DC area club...not sure

[CJ3Flyr]

I put one on 3-4 weeks ago. I do some driving on construction sites and when I pinch the rubber thingy sand/dust comes out. I can only assume that the dust would've been in the filter element. Because it's a 'new toy' I've been checking it every 4-5days.

On my '07 V6 4wd 4Runner I have noted no degradation in power. Perhaps if it was dyno'd there may be some infinitesimal decrease in power but there's nothing I can feel.:rockon:

[Crozhawk]

cool, thanks for the feedback. IF I had a V6, I'd have one for sure.

Pictures? Did the brackets bolt down cleanly into stock holes? Or, did you just hoseclamp it in and let it hang?

Findlay Toyota in Las Vegas will sell it for $98 shipped!

Unfortunately I haven’t taken the time to hook-up with photobucket or the likes so no pics. :spank:

As far as brackets/supports/clamps are concerned: On my ’07 V6 it was truly a direct, bolt-in replacement for the straight piece of plastic pipe that goes from the fender to the flexible hose into the air cleaner housing. It couldn’t have been easier. There’s no need to bend anything, buy extra hardware or anything. The support bracket that bolts to the top of the fender liner fit perfectly. Nothing is hanging or unsupported. I did take a small piece of foam gasket from the original pipe to close a gap in the foam my pre-cleaner had. As it came out of the box, there was a slight gap in the seal between the engine compartment and the hole in the fender where the 4Runner breathes through. It's as if the piece of foam tape that runs the circumference was 1/3 of an inch too short. To be clear: This seal issue for me was on the unfiltered side, on the 'dirty side' of the pre-cleaner and the gap was tiny. I am just a freak and didn't want warmer, engine compartment air in the intake system.

As I stated before, IT DOES catch dirt and I can’t tell any difference in power.

I’d say get one!:rockon:

Is there a general consensus that this will fit '03 through '08 V6s then?

Better than a consensus 'cuz if it fits the '07 it will fit any 4th Gen. I ordered one from Findlay already!

WHEN are YOU installing one??? :moon:
