Following a very dusty trip in the Vic. High Country (where we were relegated to 'whip' vehicle)- a service revealed a very contaminated air filter element.
I took it to a local truck workshop, and had it electo-something cleaned- but could not totally remove all the crap. They recommended I replace with a washable type (not foam). This cost about 40% more than an aftermarket paper type, but should outlast about 10 of the paper type with proper regular servicing.
A couple of fuel filling cycles showed a consumption benefit of a bit better than 10%, and marginally better engine response and easier high speed cruising.

My genuine Toyota (paper) air filter has the washing instructions on a label attached to it. (100 series). Good enough for me...

Morning Signman

I can tell you beyond irrefutable doubt the following re your above described experience.

(1) K & N filters do have a positive effect on performance and fuel consumption.

(2) If you go anywhere near dust, that same K & N filter will turn to a 'mud pack' in an instant and all your positive gains in (1) will disappear like the DODO bird.

(3) The Toyota genuine filter is the one and only filter for a Troopy when it goes off the bitumen.

How do I know.


(a) I have a Troopy and found out by experience.

(b) I have a JEEP which has two air filters (K&N and OEM Paper)

(c) JEEP performs better with the K&N with better fuel consumption. In dust the K&N turns to Chit.

So I carry a spare paper filter element for the JEEP (OEM $20.00)
and if changing from bitument to dirt swith air filter elements. Takes about a minute all up.

The Troopy now runs an OEM Filter 100% of the time.

There you have it.

Will you please either go back to bed or work, and shut up about the B/bird.

Damn! you are an embarrassment.

Didn't your mum ever tell you that 'silence was golden'

Ooops! forgot.

Never you mind about the B/bird. If your 'Darkie' is going as good as the B/Bird when he/she is 27yrs old, then you can make a comment.

Oi! Vey! blasted Queerlanders are all the same.

What Lucky said!!!

The reason your vehicle goes better with the K&N filter is that it is more porous....IE: it doesn't filter as well!! If you want to go to the next step (better than a K&N), try just driving your truck with no air filter at all.......it'll go great!!! (for a few thousand klicks at any rate). hahaha

Not often I agree with that old grey nomad; but on this occasion, Lucky is on the money!!!! leave the K&N in the box.

Cheers

From experience, every engine reconditioner I've been associated with won't warrant a new or recoed motor if it has a K&N foam type filter in it. Too many rebuilds of dusted motors.

You decide if it is worth it.

Are you thinking of the Unifilter or similar??
The K&N is not a foam type filter...

Me thinks you should be banned from posting any thing on the forum for a week and to be severely whipped with limp spaghetti for the unforgivable crime of using the words Hiclone & Flutch as a "teaser" ,,, lol.

I am referring to both types really, the K&n with the surgical cotton wool (oiled) and the foam type (Also oiled)

I dont know what people have about oil foam filters, i have them fitted to my GQ diesal, from 90,000ks to now 360,000ks the old girl still runs perfactly with no oil usage. I have done all the dusty roads singaly and in convoy. I still get 12lts-100ks unladen and 14 to 15 towing the camper trailer. The only down side they can be messy when servicing. The motor has never been dusted, or had the head removed. Col

This is probably the most informative air filter test I've read. air filter test
All in all K&N didn't come up to well in this one.

I use a Unifilter, the Aussie version of a k and n.

I rotate it as its cylindrical, and move it 1/3rd rotation at a time, clean n re-oil each third time.

I have a bigger exhaust system, and find it does make a difference.

All these tests may be true but in reality what they supposedly let thru in the field would prob be so small and insignificant.

K and N been around for years, used by thousands for years with no ill effects.

I think your more likely to have issues with a paper one.

If you are bush and a paper one collapses from moisture on you, unless you have a spare your stuffed, with a unifilter or k and n, if it blocks up you only need to look at it round the camp at night and clean it, refit, good as new.

Each to his own I guess.
