Hi John,
They are very good a letting more air into your engine, but also at the
same time let more dirt in.
There is quite a good article about it here:

Hi Guys
Just wondering if anyone has or is using a foam air filter, the type which is supposed to last for ever but needs a cleaning and oil changing.
Are they any good or too messy and not worth it.
Any idea what the filter rate in microns is of the normal paper filters.
The foam one I saw says it filters down to 4 microns is that good .
cheers

Hi John,
You can find a reasoonable write up at:
http://www.lcool.org/technical/80_series/filters.html
Personally I think 4 microns for an air filter seems quite large.
Looking over archived messages the general consensus seems to be to
either stick to the factory paper filters or the factory foam filters.
A lot of people get lured to the likes of K&N filters for increased
performance however the increased air flow usually comes at a cost
which is more dirt in the engine.
Additionally for a standard 1HD-T in the 80 series you won't notice
that much of a performance boost from something like a K&N - with an
intercooler and more boost you might do. In fact several people on the
LCool lists have reported noticing a performance boost when they have
remmoved the K&Ns and gone back to factory paper filters!

Hi John (and rest of Elco group, where I've been lurking silently for some
weeks!)
I use a UniFilter air filter on my 1995 FZJ80. They are Australian and made
of quite dense foam - similar to that used in off road motorycles. The
don't offer the same 'high flow' as K&N filters - and have, I believe,
similar filtration properties to the OE filters. The advantage though is
that they can be cleaned and reused - which is very handy on overland trips
or dusty conditions. The filter has two foam parts - and outer 'wrap' which
you can clean most of the time and the inner foam filter which usually stays
quite clean, because of the wrap. The filters also come with a 'cage' to
support the foam. You can clean the filters with petrol or filter cleaner
and re-oil with filter oil.
UniFilter are Australian - I had bother getting them in the UK, so they just
posted 2 over for me from Oz - the postage was amazingly cheap, I seem to
recall.
Anyway - hope this helps,

Hey Julian
Thanks for that info do you know what the micron size is on the standard
filter.
Just off topic but the cruiser has to go back to Toyota very soon cause it
is loosing a lot of diff oil at the wheel.
And yet they were supposed to replace all the seals( which I gave them and
the inner seal was Toyota) when they stripped the front end.
So I guess a bad fitting I hope.

Hi All,
Just to follow up on this I have been in touch with
http://www.greenfilters.com/ who make K&N style filters to ask how they
thought their filters would cope in dusty conditions and also what
service/clean interval they recommend in dusty environments.
The bottom line is that they don't think that their filters are
appropriate and think that we would be better off sticking to the
factory paper filters - a nice bit of honesty!

fyi: just a warning if anybody out there has a safari snorkel. if i remember
correctly - safari (on their website) say that the use of oiled (k&n)
filters are not advisable with their products. from experience i have found
that a snorkel cuts down on dust etc anyway so paper filters, which are
cheap and easy to replace (except toyota ones) are the way i went.
also when fording rivers or stuck on really dusty roads, i just turn the
head of my snorkel around so that nothing is "ingested" by accident.

Have you seen those conical filters that fit onto the safari snorkle?
Kind of like a pre-filter that knock out the heavy particles
Seem like a good idea for dusty conditions but haven't heard any
feedback from the horses mouth....

in really dusty stuff, best to put a cyclone top on the snorkel...

Re> In really dusty stuff, best to put a cyclone top on the snorkel...
I wonder if the cyclone reduces the amount of air being rammed into the
engine.
Might be an idea to fit only when required - which is probably most of
the time?
Cheers

It might do but not so as you'd notice and it's better than just spinning the
top on the standard snorkel head. You could easily swop them over if you have
the space to store the tops... or just run with the cyclone al the way.

i've worked and lived in africa since 1991 and i honestly have never seen
one of those "cyclone pre-cleaner" on a working vehicle (seen a few in the
keg car park in jo'burg though!), but then again i've only ever lived and
worked south of the sahara - maybe it's different up there.

Jeremy,
Plenty of them in Libya, Algeria, Mauritania, Mali .... all those
areas where dust is a problem. When you pour out a handful of fine
dust from the bowl at the end of the day you know they do work.

Hi Niall,
You will find that the 'RAM effect' from snorkels from people like Safari
is pretty negligible.
I think Craig Vincent on the list here has done some tests and found that
they are actually more restrictive than the standard air inlet
arrangement - you only really benefit if you make your own 3" snorkel.
