Air Filter options for 70 series Landcruiser

[Slideways]

I'm trying to find options for my diesel BJ73 Landcruiser with standard airbox, currently its a 3B but have a 13B-T that will be going in soonish plus a 3" steel snorkel.

Does anyone know a good supplier for a good re-usable aftermarket air filter like K&N, Fram, Unifilter etc?

Also has anyone got suggestions on which to go for?


Cheers

Pioneer Auto Parts are the NZ agent for K & N filters. I would think that they will have a store in Wellie. They certainly flow good amounts of air (tested various size K & N's on a dyno).
They can also have a pre-cleaner element which wraps around the normal oiled cotton filter and which is easy to take off and shake out. I use this on one of my performance vintage cars that sees a lot of high speed dirt action.
must find the money to get one for my Prado .....! Oh for a full time job.

With these re-usable filters, like everything, you get what you pay for. A lot of them restrict flow rather than improving it. K & N's don't.
Some of them are not particularly good at fine filtration i.e. dust and dirt. Can't comment here on the K & N, as I have not compared the figures, but I believe they work well. They are used by a large number of race teams, CORR and off-road race included.
The important thing here is the type and quantity of filter oil used.

I got one of these of Rob (Naenae Tyres), washable filter...


the leading edges of the filter will need sealing but this is a 2 min job with a finger and some sealer, the pipe you can get from a place in the hutt road....(otherwise I may have a bit left)

I also run a "snorkel sock" at the top of the snorkel ....which Rob has as well

Thats quite cool Jerry, I have a use for that on another car! But for the cruiser I want to keep the big factory air 'box' to catch any water or wild life that goes into the snorkel so need something to fit that.

I did think about cutting a hole in the side of the air box and welding in a 3" steel tube then mount a K&N pod filter inside. But would be hard to make the lid seal since I wouldn't be able to use the centre bolt/wing nut because the pod filter would be in the way. If that makes any sense!

Roughly how much was your tube filter jobbie?

Supercheap will probably have a Unifilter for a 3B. Had one in my Safari and it paid itself off 5 times over.

Cool didn't realise Supercheap supplied Unifilter. I've only seen Fram there, will have to give them a call

[Taz]

Yeah neither did I until yesterday. I saw the oil and some smaller filters up on a wee shelf behind the counter. Failing that a 4wd specialist shop will either have them or know where to get them.

We've spoken about your starving filter before, but for your benefit and others, I will repeat myself and add a little more.

There is No Way that your engine will be able to flow anything like the airflow it needs through that black, I assume carbon fibre, air-box. If it had no filter in it, it may but probably not, and what's the point.
Think about the size of a typical filter on a V8, about 50 to 75mm high and about 350 to 400 outer diameter. (air flowing from outside filter through filter) That is a cylindrical surface area of between about 55000 and 95000 mm2
Your set-up looks like 130 high by about 75 inside diameter. (air flowing from inside filter through filter) A cylindrical surface area would thus be around 30500 mm2

Therefore your filter is about 30 to 50% of the size required going on a cylindrical surface area.

However the above does not include the depth or thickness of the filter.
In the case of a normal style V8 filter, about 50mm
and with your bling thing about 15mm
So V8 actual filtration area is between 2750000 & 4750000 mm2
bling thing filtration area 457500 mm2

So really your filter is between about 9 to 16 % of the filtration surface area that you require!

More to come on other installation bits later.

Jerry I would suggest yoy go buy a filter that will not reduce your torque HUGELY nor richen up the air/fuel ratio massively.

the speed shop in high st lower hutt can get unifilters in.
forget the name of the shop but near melling road.

Are you looking for something like this?

[skid]

get one like sadams in a K & N, they are washable, reusable, oilable etc etc etc

you will never need to replace it

[zookfest]

got k&n's in my 70 and my 60 dam good filters and washable,buy it once and thats it

[Slideways]

Speed shop, do you mean Road and Track? I'll give them a go, point of interest though - the owner is soon to be ex-owner. They change hands on August 1st.

I'm pretty keen on a K&N but would be good to find the best price since they are normalling pretty pricey.

Have used K&N's before and have been good but always had universal 'pod' type filters, I'm guessing something to fit a specific vehicle like the 70's will probably demand mega bucks, yeah?

Yep...the big V thing next to it, yep thats what Im after

Don't know about K&N but I paid $80 or $90 bucks for my unifliter. The replaceable ones were $40 so I didn't think that was to bad. + $12 for the oil. (This was 2 or 3 years ago so they may be a little more now)

road and tracks the one, k&n's are twice the price.

Bought a Unifilter for the new, 16 years ago, Patrol yesterday. $95.
