Apologies if this is a stupid question and / or it has been asked before. My 1990 carb mini cooper has a K&N cone air filter, which is filthy. How do you take the filter apart to remove the cotton part of the filter for cleaning? There is very little room between the top of the air filter and the bulkhead, and I'm a complete novice, so I thought I would ask for advice before making a mess... Thanks in advance for your help.

Whip the inlet off, with carb still attached, you'll need a 3/8 ratchet, extension, wobble extension, 1/2"(13mm in Church of England) socket. You won't have to disconnect anything it'll lift up out the way enough to get to the retaining bolt of the filter. A good clean and re oil and be good to refit.

Thank you very much. I'd better start by getting the tools you mention! Where is the retaining bolt on the filter? Does the top of the filter simply unscrew and then you can lift the fabric filter material out of the top?

Ahh the ease and simplicity of a reusable air cleaner.
No need to remove the intake system with a paper filter housing.

Most KN cone filters should just have a nut on the outer metal plate. Simply remove that and the filter element should come out with a little wiggle

Thanks everyone! That picture was really helpful - I managed to simply undo the nut on top and wiggle out the filter.

Be careful when cleaning it.

 

Roll it about in a shallow tray to free the dirt on the outside, rinse it from the inside. Don't dunk it, so what's on the outside can get in to the inside.

 

It's best to take a couple of days: wash - let it dry for a day, oil - let it disperse for a day.
