Air filter options for 3.5 petrol Jack

I use Unifilter - they have a site - is actually composed of 3 levels of oiled foam protection - the outer one gets filthy - the middle one a bit dirty - the inner one is clean forever. You need PVC gloves, a couple of litres of turps and a bucket for the cleaning - can be a little messy the first time round - and you need to dispose of the turps of course - I like them, mainly because I'm denying Isuzu (or is it Holden) the opportunity to charge me rip-off filter prices !, Check Unifiter for their distributors..... you can get their really sticky oil at the same time. If you buy two of the outer sleeves (stripper), you can take a spare with you, pre-oiled....saves doing the cleaning while you are away on a trip. Warning - fine droplets of oil can pervade your system - can upset gas sensors in there - might give you a computer reading on the dash..... such as in my 3.0L TD in the 99 Jack. Computer doesn't like it be the car is quite happy !

Hi Rob,

I have a finer filter. This has now been taken over by Unifilter.

It's been in their for around 4 years and I'm quite happy with it. I paid around $60-$70.

The oil doesn't affect the 3.5V6 ecu as it does the 3.0TDi. I recently pulled the mass airflow sensor out and their was no oil affecting it. I still gave it a clean with some electronics spray cleaner (from Jaycar) anyway.

Check www.unifilter.com.au

Thanks guys. Hmm, there seems to be some uncertainty about how the oil affects the ecu sensor, and whether this upsets the TD or petrol or both. Another person (4WD shop) I spoke to said avoid the oiled foam filters for precisely this reason.
The unifilter website claims improved airflow and therefore economy/power. Can
any of you confirm this? Price wise - seems about the same as a Ryco from Supercheap (don't know about dealer prices).

Try K&N Filters. I have one on my 2.6L Rodeo petrol and have never had an issue. Mine cost $100 which is less than 2 paper filters. Plus about $25 for the cleaning kit. I'd never go back to paper ones again. I did actually notice a gain in power when I originally fitted it. I can hold gears longer on hills now etc.

I can't see how one of these would let go of oil which would give problems like stated above. It's not of foam construction like the Unifilter but some sort of surgical mesh from memory.

Thanks for the replies guys. There are more options out there than I expected.
Are servicing intervals for washable filters (either foam or the one Utie mentioned) the same as for paper?

g'day, I have a 2000 TD jackaroo and have put a K&N oiled pod filter on. I have had no problems with oil on the throttle positon sensor, however i have read (on this site previously) about unifilters affecting the TPS. These pod filters are used in high performance turbo cars, however there is some controversy over the intake of hot "underbonnet air". K&N claim better power and fuel economy but lets face it putting a "slightly less restrictive" filter on your car is not going to do that much, especially with a standard exhaust. The filter is loud though and some people might not like the "blow off" noise between gear changes. I have had the filter for 2.5 yrs and considering a standard filter costs $50 or something i reakon I got my money back (K&N cost $150). Anyway your probably best keeping the jack standard!! Cheerio.
