High Flow Air Filter SDV8

[Disco4SE]

Hi all,

Just wondering if anyone has installed an aftermarket high flow air filter to their SDV8?

Cheers, Craig

You mean like a K&N?

Don't.

Unless you want to dust your engine if you use the car on dirt/in the bush.

I'll let someone else link to the relevant thread, I'm on my phone and Tapatalk is useless for searching.

I did do a search and couldn't find anything.

I am looking at a dry high flow air filter as opposed to an oil type filter like K&N.

Cheers, Craig

Wouldn't it be better for the engines longivity to use the stock air filter to make sure No dust gets into the engine, Just make sure you replace it if it gets too contaminated.
Many people neglect their air cleaner filter when doing a service, I tend to replace mine every 3-4 5000k services or even more often when i have used the truck in dusty conditions.
I don't own a Landrover TDV8 But my D2a petrol V8 and my 79 Series TDV8 are fitted with stock air filters and I haven't had any problems with a restricted air flow in either of these engines.
Both trucks are fitted with a ram head snorkel which does slightly increase the airflow But I don't think that they make that much difference overall.

What makes you think that the 2 LR filters are restricting performance?

Nothing wrong with the original air filters, just looking at improvements.

The ones I am looking at actually have a better filtration system yet better airflow.

.

That's far too frequent except when driving on dirt/off road every day, and even then it might be too frequent.
I still did 20,000km air filter changes on the Tdi when I was still on the farm.Ben/Isuzurover tested the Donaldson I used and it had plenty of life still in it.

Air filters become more efficient the more heavily loaded they become, right up to the point the pressure drop is so great they collapse.
You'd remember seeing pressure drop indicators on tractor and truck air filter housings.
That's when you change the element, any sooner and you are wasting money.

In my experience people change them too frequently.

Having said that the panel filters Land Rover used on the TD5 were pretty ordinary and only a few brands of elements sealed properly.

I'll kick up the laptop later and dig up the air filter testing threads.

Hey Guys,

These are the filters that I have been looking BMC Air Filter High Performance Air Filters (http://www.bmcairfilter.com.au/). Might answer a few queries.

Cheers, Craig

As per Rick130

I remember reading a thread on here that tested different types of filters. From memory two of the filters were paper element, a generic brand (say Repco) and a AC Delco or something. The AC Delco was the best performer in both flow, filtration and pressure drop over time with dust added. The generic one was only third or so, but the foam and cotton filters didn't fare very well.

Have a read of this thread.

They are a oiled filter (at least for 4wds) so not good for our cars.

Didn't realize that is an oiled filter, however I did email them and asked them to confirm.

I would never use an oiled filter. I run a AFE Dry filter on my Grand Cherokee and it has been great.

Thanks for the feedback everyone. Much appreciated.

Hope to pick up my new (second hand) Sport tomorrow afternoon [bigsmile1]

I just followed the link you put up and looked at the offroad filters.

In there it says

"BMC air filters are also designed and produced to ensure a higher air flow than OE filters, producing less than half the pressure drop when compared to paper filters. BMC air filters allow more air into the engine, while providing better protection.

As cotton is a natural material which can be reused several times the filter can be washed with a special detergent then re-oiled, saving the cost of changing the air filter each time the vehicle is serviced. The filter can even be cleaned and regenerated in the outback, with the handy aerosol service kit. BMC air filters have a general lifespan equal to that of the vehicle."

Italian version of K&N.
Did anyone notice you could see the car radiator badge through it as he removed it?

They obviously have a MAP tune and no MAF.
Not much dust on a racetrack.
