Well i use Genuine oil filters and air filters from Karcraft or Fred Smith.

Do we know who makes the genuine ('cause I doubt its Land Rover).

I suspect that LR has Coopers make them.

http://www.master-filtration.co.uk/coopers.htm

Made in the EU for the moment for what that is worth :roll: .

Often parts are made under licence by others to the vehicle manufacturer (OEM). The licence has a time limit after which the manufacturer of the part can sell the identical specified part under its own name/brand. So LR Filter = Coopers Filter without the LR mark up.

And the proof is:

If properly installed the Coopers filter does not leak oil therefore it is not made by Land Rover :wink:

The OE ERR 3340 filter is made by Delphi in the UK. (Delphi used to be part of GM, but was spun off several years ago. The US arm has since gone into bankruptcy.)
It has very interesting construction, using no endcaps as the cellulose pleats are glued together and dimpled to keep the spacing correct. The media is very thin.

Coopers is part of the Italian owned multinational conglomerate SOGEFI, as are Crosland, Fiaam, Fram (Europe) amongst other filter companies. (Fram US is owned by Honeywell)

I suspect quite strongly that the L25195 Purolater (which is the correct cross reference for the ERR3340, NOT their Z89A equivalent. Check out www.purolator.com's online catalogue, I have had it confirmed by Purolator engineers in the US ) is also a Delphi filter. It's specs are Beta 2=25, beta 20=40, media area of 312 sq. in. 14-16 psi by-pass. Its capacity is 9.52 grams. These are fairly average specs.

So can we assume that a Coopers filter (made by the SOGEFI conglomerate) changed at 5000km will do the job?

I've never even seen a Pommy Coopers filter, but if it is made to meet OE specs it would be fine. I've used a few Crosland filters over the years, and they have been well constructed when I've pulled them apart. (it is a sickness, and I am seeing someone for it..)
Most of the Poms on the other Land Rover boards I hang around swear by them, if that helps. :wink:

FWIW, I always refused to use Wesfil air filters as they used only half the paper of an equivalent Ryco cousin.

I guess that is the issue..We trust in OEM

It's about comfort zones.

Rick mate, you really should get out more y'know.

hehe, I actually use a filter that blows away an OE spec one on all areas, (filters down to 1 micron, beta 2=7 which means it traps 50% of 7 micron particles in the relevant SAE multi-pass test, beta 75=22 or 98.67%, dirt holding capacity 38 grams, synthetic media = much greater service life, etc), but it is a marginal fit at best size wise, and so can't really recommend it.
