Well as the topic says, i am looking for a higher flow air filter for an 80 series, what we have at the moment is the standard paper filter but since then there has been the turbo added, now i assume they changed the filter to the turbo model but it is still a paper filter, has anyone tried foam filters in the same shape with any improvement, i have also seen people put a pod filter on the top of the snorkel? anyway have any comments? positive i hope :) or any info on a good place to source them?

thanks

Joe

Hi jbwetzels.
I am onto my 3rd pajero & have used finer filters in each vehicle.There was certainly an improvement in performance. My last 2 vehicles were fitted with snorkels & there was more induction noise when a foam filter was used.
The filters are easy to clean & I wouldn"t go back to using a paper filter.

I have used uni filters for years with good results, more power.
I have NEVER found dust in the inlet tract, and their is some interesting info on the lcool site.
At a club day all the standard filter vehicles inlet tracts were tested with a white cloth and all had fine dust in them, next the vehicles with foam filters were tested and not one hads fine dust. That is good enough for me

DO NOT USE FOAM FILTERS WITH A TURBO. Yes I am raising my voice. Turbo installers will or should tell you that if you have a piece of foam part company with its mates it can bleep ter the turbo fins. Don't believe it, we neither did I till I saw the damage!! Stick with the paper filter. They work and can be hosed clean.

What happens when a piece of the paper filter tears off and hits the turbo?

In my view, this is just as likely to happen as with a foam filter.

My foam filter has NEVER had a piece tear off.

Joe,
For what its worth, my Factory Turbo 1HD-FTE uses identical air filters to your 80series. I don't think you'll get a better filter, and the factory air filters are washable in water.
I had Finer Filters on previous LandCruisers and they are a PITA to clean.

Phil, You are dead right. I had foam in the 80 diesel till I fitted the turbo.
Paper are the way to go but there is no helping some.

Paper might be ok if you want to keep forking out $ you should only wash paper 3 times. Foam filters clean up easy with petrol etc and last for ages, Ive not seen any foam break away and have used them for years, if kept oiled they work better than paper trapping all the very fine dust in the oiled foam.

I am only telling you what the turbo manufacturers tell the installers but if you know better go ahead and drive with your fingers crossed. Sometimes I just give up.

I have been using foam filters for over 20 years.
Usually get 5 to 7 years out of a filter before the foam starts to break down.
I am not sure but washing in petrol or turps may not help.
I wash them with liquid laundry detergent now, then rinse and dry.
If you are washing them on a regular basis, you see the foam breaking down.

May go back to paper now that you can not buy a spare outer, only a whole assembly. Used to carry a spare outer and swap over every day or two on dusty roads. Washed the filter when we did a small clothes wash.

Gday Edmund!
You must like the Finer ritual - but their instructions are a bit different - kerosine slipping through your fingers, then off to the laundry sink to wash it in dynamo (I trust Anne approves), then hang it out with the undies to dry :-))) Not to mention putting the Finer Filter oil in the Microwave to soften it up - eventually I learnt the trick of slipping the foam into the gladbag to oil it. I guess you may have seen this comparison:

And on another note, well done to you for sticking up with whats right at you know where. Keep in touch.

Cheers
Phil

Oldplodder,
With the Toyota washable filters, I have two filters and alternate them. So I use one while washing the other, and letting it dry out. And I carry a spare out bush, but must say the 79series snorkel does a pretty good job of precleaning the air. As far as cost goes, $45 for 40,000k of use per filter is fine by me.

G'day Joe,

Not sure if it's the same for your 80 as my 1HZ 100 series, but the factory air filter from the V8 100 series is quite a bit larger than my original, and it fits straight in to my air box. Has the benefit of being a washable paper? type (instructions are on the underside to do so) and better airflow than my original. Both of the places I have had turbos fitted have recommended not using foam type filters. The paper type jobs won't flow as much, but they will filter more effectively over extended periods.

I remember seeing a link to an article on air filters on here a while ago, had some very useful facts/comparisons between quite a few different types of filters. Helped make my mind up Someone might be able to help out....

(You can have my K&N foam filter real cheap if you're in Perth!)

Cheers,

Rossco.

Sorry,

Link to original site doesn't work any more, but this is along the same lines.

Air filters are an interesting subject and been subject of
many posts - and bottom line is that there is little difference
in air flow , and virtually no effective difference in practise.
(assume engine tuned for each)

This is because even though some tests show small differences
the difference is only effective when near full throttle.

I.E. Even if you had no air filter it would make no difference
until at full throttle because all below this you aren't restricted anyway.

So why do I use Uni-filter ?

Paper filters are just a series of small holes , and dust below this size
just goes straight thru.

One of the most dangerous things to do to an engine is get a new paper air filter
before going bush - its pores flow most then.
The filter has to be pre-loaded with dust in effect by 1000km of normal driving.

The different type of operation of oiled foam means that it works from go
and works best soon after cleaning.

The paper filter has an advantage in that it normally fails safe, it just clogs
up and chokes the engine.

The oil foam type , can get into a mode where by theres little sticky oil left
and dust passes thru.

In general the foam can be better but only provided it is maintained well
which I find easy on trips.
By far the biggest danger is it not being installed correctly or over oiled.

If you end up with one never wash it in petrol as over time this weakens
foam and pieces could end up in your engine.
Also clean it regularly (5000km max)

Most of air filters tests I have seen via internet links do not use
dust of same characteristics as we get in Australia and results are suspect.

To validate my Patrol's air filter - I attached a vaccum hose and sucked air
thru it whilst monitoring the air flow meter voltage.

Paper and Unifilter were much the same - but playing with folding of outer layer
in various ways caused increased air flow, above that of even no filter
and so I now do it this way.

Paper filter is fixed and could not therefore be adjusted to match Uni.
