Are Toyota fitting Hyclones?

yep seen one on an underground ute. Are you sure it is standard?

Come on Mike,

What sort of toyota and how old, or are you saying that it is a new car straight of the showroom floor?

You are aware that exploreoz only lets you post a joke on Fridays? lol

Regards Boo Boo

See if you can get a second one to fit in there - should make the old girl go even better!

Part of the centrifugal dust pre-filtering system?

Mike,

They are real and standard and act as a pre cleaner. What they do is to swirl the air and any water that has entered the intake pipe will be pushed to the out side of the tube and will then go into a sump further along the plastic pipe.

The air will then go into the air cleaner where the air enters the air box.The air gets spun around again. This again will push all the heavy bits that got past the first pre cleaner to the out side of the air box and then fall to the bottom of the air box and collect in the sump. If you look under the bottom of the air box you will see a small tin can shape sump. Un clip this and all the bugs and dust will be contained here.

I found exactly the same thing at the front of the air box behind the headlight when I removed the intake system to fit the Safari snorkel. This was on my 1990 model 80 Series 1HZ Landcruiser.
I was so surprised that I posted on the same topic.
So does this mean Toyota have been fitting "Hiclones" for 17 years???

Yep, I removed mine after I found it in my 100s, and my fuel economy plummeted. Fitted it straight back in after a couple of tanks and it was back to normal. I've since fitted 3 more and now I drain my auxillary tank once a week and sell it to my neighbour!!

Guys......now you know where Hiclone got the idea fron....heres something to try.....cut the fan off the long tube, leave about an inch of it still on the fan.
Drill a hole in the centre of the fan slightly bigger than the centre bolt that holds the filter together.....put the fan up in the hole at the top of the aircleaner....you now have a toyota hiclone.
Get a pack of 6's and open the first with the nearest door jam :)
I love my Toyota

NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Guess what?

There was a big one of these cyclone filter devices in my 76' model FJ40, so Toyota have had "Hiclones" since the 70's.

Wouldn't surprise me if the original 3 speed as found on the Snowy River project had the same air filter as the FJ40!!

That must be why the FJ40 got 16mpg otherwise I'd never have afforded to run it!!

Must have been standard in alot of the toyota's as my 2.8D has the exact thng behind the air filter inside the metal casing. Steve M

My 1995 2.6l petrol Holden Rodeo also has one fitted as standard right at the start of the intake tubing.

Hi Mike,
Toyota have been fitting these for years, i've mostly seen them on 75# & 79# utes but have noticed on hiluxes and others as well. They ususally fit them in place of a snorkel, or better put it's the end cap of where your snorkel would go. the 100# i think have kind of a split system where any water entering this hiclone would be pressurised and forced out somehow. otherwise a snorkel would be as useless as an ashtray on a motorbike when your headlights are floating somewhere around the water line of a river.
Cheers :)
