    Question Anyone used the K&N air filter service/cleaner kit? (or have a bit of sense? lol)

    Got one of these off of the bay & just done the cleaning process last night. Left if overnight for the drying process.

    The oiling process makes no sense to me:

    "apply oil liberally to the dirty side only ............... see figure 3"


    Now to me, the dirty side is the underside of the filter (as you put the filter in the box, it'd be the side you can't see basically) as this is the side which traps all the cack.
    Have a look at "figure 3" and the chap is clearly oiling from the top side (look in air box it'd be the top side you're looking at) which to me is the clean side.




    Not very clear instructions.

    So as i'll be doing this later...anyone know what the proper way is?



    EDIT: http://www.knfilters.com/cleaning.htm

    Just found that.

    I can't see as i makes much difference, but i disagree with what side they call clean & dirty. Just in case it does make a difference that i'm not aware of, then i'll hang off for someone to shed light on it

    You've reminded me to give mine a clean but I can't find my spare filter lol. Just looked at the instructions and saw the picture. I think it's there for reference only. Always oil the dirty side.

    The pics are misleading IMO.

    I'll oil the dirty side as in what i call the dirty side then - and that's the underside of the filter that traps the dirt


    Is it even necessary to do this process (cleaning?) Mine didn't look all that dirty, but after i'd washed out the cleaner in the bath, there was a bit of cack that came out, but a lot of pink colouring.

    Ummm, what question are you answering mate, because that wasn't mine

    I know the process. Question was which is seen as the "dirty" side, as my view, and the image they use differ. I seem to share the same view as Tom - dirty side is the underside. That was the only thing i had doubt over.


    Anyway, it's done now. Used much more than the "48ml" they recommend, as the clean face wouldn't turn red throughout. Ended up using about 70ml in the end.

    Should be fine, some people will tell you over oiling is bad but it wont do any harm as k&n have proved.

    I have found that my k&n has been pretty clean the last couple of times I rinsed it out, the pink coloring is just the old oil washing off

    Basically the "dirty" side is the underside of the filter thats faced downwards towards the bottom of your enclosure. Re-apply the oil / protection to this side only.

    Aye that's the side i chose in the end

    I figured so long as the oil wasn't dripping out, then it's good to go
