GU PATROL AND FINER FILTERS

Depending who you talk to, which leg your standing on, and what day of the week it is, is to if they are any better or not.

I have been given 4 main Finer Filters, and 2 Precleaner ones for nothign from people who thought they werent worth the effort!

I ran them, and didnt find any difference, (TD42T).

The OEM filters are only $20 for mine, and I'll stick with them I think!

The oil in foam filters is known to destroy the air flow sensor in the 3.0 patrol ... a part that costs >$1000. I personally use only the genuine air filter, which is lightly oiled anyway. I have a snorkel fitted, and when going through extreme dust (generally convoy driving), fit a snorkel sock (over the snorkel inlet), which significantly reduces the dust load on the normal filter. Because the oil is at the top of the snorkel, and the paper filter sits before the airflow sensor, this provides maximum protection, without risking damage to the sensor.

CheersSo much to see, too little time ...

The only real advantage is if your OEM filter is fairly pricey and you do a lot of km's. Most of the finer filters I think are around $60 - $100 mark so if your changing your filter every 10000km and your OEM filter costs $30 bucks then it doesn't take long to recover the extra for the FF. I've had a finer filter for 5 years and still on the original bottle of oil (500ml). Any power or efficiency increase is 3/5 of bugger all. Another advantage is that you can clearly and easily see when it needs cleaning and it requires no mods to your vehicle.

My $'s worth -
Due to the high cost of a paper air filter for my Rocky I used a finer filter for 3+ years without any problems until about a year ago when the turbo developed a small oil leak. My mechanic said $1k should cover reconditioning the turbo which should fix the problem , another diesel mechanic said get rid of the finer filter,its restricting air flow , go back to a paper filter and see if that fixes the problem. Went back to the paper filter no sign of a leak since- I believe the finer filter was restricting airflow and putting presure on components??
It may cost a few $'s more but I will stay with the paper filter.

As Andrew O said, they will clog your air sensor and stop the cars management system. Don't do it.

Nissan filter in excellent and actually inpregnated will oil anyway. Use the genuine part in this instance. NO QUESTION

cheers

Mick,
When I did my power upgrade I asked John Whittaker of Dyno tuning &Turbocharging (they did my upgrade) the same question, his reply was to stick with the standard Toyota air cleaner.

Arguably, the best filters on the market, in terms of air flow and longevity, would be K&N. However, the do not make one to fit Patrols, yet. Suggest a phone call or e-mail, to keep the pressure on to have them produced. They are a cotton spun fabric that filters finer than paper, flows twice the air so very good for turbo's, and are washable and reusable.

The K&N filters get my vote, been using them for 8 years (5.0l Commodore, 2.6l Rodeo & FJ1200 motorbike). Better fuel economy (slightly) and a heap more power (even the missus could feel the difference on her first drive)

A bit dear ($120 for the car, $140 for the Rodeo & $95 for the bike) but cheaper than constant replacement of the paper ones + all the above benfits.

Check Repco, a mate just bought one for his Hilux there and they had the best price he could find locally (Brisbane)

k&n are the go, noticed huge difference in power, if you get one it is extrememly important to clean regulary, every 10thou, more in dust. They make one for the gq patrol, dont know why they wouldnt for the gu
