Well, after purchasing the necessary service items I found out my TD4 has a K&N filter fitted... I've stuck the new one in for now, as the K&N is filthy.

The question is... how do I clean it and do I need to oil it when I've cleaned it all up?

Will anywhere clean it for me if I send it off? (Can't be bothered messing around with solvents etc).
 
If its the metal mesh type then its a wash in petrol and then dip in oil and shake.
I will do it fur £20 plus p&p - and so wud Mondeo if ya like?

I wud even send it back in a re-sealable bag - so the posty dont get too oily
 
Follow K&N instructions - you should be able to get them off their website.

Be carefull not to over oil it or the excess will contaminate the maf sensor and ruin it.

I prefer BMC or ITG filter as these are preoiled for life.

That's true.
Depends upon how dusty the environment you drive in is too I guess. I can imagine Freelanders going in some dusty places!!

I just give my BMC one a vacuuming every service to get rid of dead insects. It still looks clean after 10k miles.

ShotgunDrew,

The Elise gang clean them ourselves all the time.

Clean filter in warm soapy water.
Dry using the 'Windmill' method, hairdryer method or simply leave in the airing cupboard over night (ask the misses first! I got a right bollocking).
Pop down to Halfrauds and get some filter oil for a couple of squid or buy some of K&N's own for a few squid more.
Once dry, spay oil on and refit...jobs a carrot!

K&N aren't that bad, they do breath easier than factory fitted but there are a lot better ones out there. Also, if its an after market filter you should tell your insurance company, having it fitted could invalidate your insurance.
Cheers

Hi,

I used the "windmill" method as well, used an old fan I recuperated from an old diskunit, as this diskunit was something of the late 60's it's not the "mini size" as these days yet which resulted that I almost had to nail the filter down to the ground in order to not being blown away ..:D :D :D :D
But it did the job magnificently.:) :) :)

It's not necessarilly the size of it but what it produces, it's a monster, it has an 1.08hp motor on it .. Once I used it to 'support' the wind while BBQing at my neighbour, we had to collect all the sh.. in a hurry as it was setting fire on everything around it .... it blew everything out of the BBQ set. When I put the plug in the power everything needs to be fixed pretty well as there is so much torque on it, unbelievable.:)
