JR Filters

[-Nemesis-]

Anyone used these? Am looking for a decent filtering pod filter, I know K&N are good for performance filters, but better filtration would be nice....

There's a mob selling them on eBay now and they seem the goods. They're basically K&N filters a la French style, but claim a superior filtration level of 2.8 microns, better than K&N. Oh, and they run about half the price and have a lifetime warranty...

This is the mob selling them:

This is from the JR filters site:

JR FILTERS has been founded in the year 1992 to develop and produce high technlogy air filters.

In the year 1998 our company received the certificates of ISO 9001

JR FILTERS producing company was accepted by the German government ( KBA ) which is the highest possible award which a firm can receive.

Superior filtration of JR Airfilters :

The only filters that will protect your engine against particles as small as 2.8 microns.

Remains 99% efficient.

Clean and re-use every 20 000 kilometers.

There is no such thing as a "decent filtering" pod filter

How fine do paper elements go though? Not that it's an option for me.


I need a pod filter for my setup so it's either K&N or these ones.... I'm not trusting a no name shitter, and from the only scientific pod comparison I can find (from an auto mag) the K&N had the best filtration (which proves your theory, I don't disagree) over the expensive Apexi and rice brands etc. If these JR's claim finer filtration then I guess it's worth a shot.

I found the other day that K&N make pre filter bags for pods, might source one of them for convoy driving. Or even get Uni Filter to make up a foam cover.


For what it's worth, so many people run K&N's (search any 4WD forum) and I don't know of any who have had engine failures from lack of filtration.

Well, first of all, filters aren't sieves. So giving them a "micron rating" makes no sense.

e.g. - see below:


The pod filter in question may remove 50% of 2.8 um particles (at best, and dependent on flow conditions), however it is easy to design a filter which can remove much finer particles at higher efficiency. Cellulose (paper) filters are usually VERY efficient.

Why???

Car mags know SFA about filtration. There are a few studies on here (including one I did) which show that Krap_n_ENN filters are just that. You may as well fit no filter as far as I am concerned.

Search and you will find. I know of several...

At the end of the day - it is your money and your engine. Personally, I would not run either of the two filters you mentioned even if hell froze over, but what would I know, I have only been designing filters for 12 years...

How come you need a pod filter? Can't fit an airbox anywhere?

Precisely. Too custom, no room. The only downside to my setup and a small engine bay.

It's either run a pod off the front of the charger, sitting partially through the radiator support panel. Or lose the supercharger, but it's too much fun for that.




No enough room to run a big enough pipe back into the engine bay, have tried a few times but it's too tight.

I don't suppose it's possible to design a self supporting filter like a pod then is it?

Do you have any better pics of the space you have for a filter???

How much room exactly?

EDIT - these are the most compact filters which will actually work.

They are built under licence from donaldson using the powercore concept - which is the most compact way to make a REAL air filter that anyone has come up with yet.

There is no reason you need to use them with an airbox, but you may want to put a splash guard below the element.

They are not cheap, but they are guaranteed to only need replacement every 4 years or 100k km (when used on-road).

I'll try get some.

Basically it's too close to the panel (2" max), and too much behind the headlight to fit a filter on directly.

At the moment I have a 45 degree pvc elbow pointing down and towards the intercooler. There's a pod on the front that sits in the front grill between the headlight and cooler (on an angle) with a custom cover over the front so it's not cop bait.

Though if I take the cover off it gets fresh air from outside the engine bay and will almost lift a front wheel heheh.

That's the other thing, the filter needs to be able to feed a 4" inlet and somewhere in the 4-500fwhp range.

Can't go into the mudguard instead maybe?

Looking good btw, how about some more pics?

Will try get some mate, here's a quick vid when it was only running about 5psi (now about 9)

In the meantime I may have found a cheap solution for dusty conditions, thanks to the interweb. Cheap vacuum filters:

IS IT POSIBLE TO MAKE AN AIRBOX USING A PANEL FILTER TO FIT YOU APPLICATION?
