Hi. Took my airbox apart yesterday to see what lurked, and found what i think is a K+N filter (Its orange cotton gauze rather than the usual paper i'd expect). But, its filthy, as in caked in crap, full with random crap.
How shall i clean it? I know they have a 'million mile warranty' on them so it shouldnt need replacement. I thought of blasting the crap out with compressed air but im not sure that would do it.
It's best not to use compressed air as it will damage the cotton filter. You should wash it with K&N detergent and warm water, allow to dry fully and then apply the K&N oil.
The oil is what catches the dirt. But don't over do it or you will restrict air flow

head and shoulders best and then use some WD40 to re-oil it and your fine worked for me use it on the xantias one and youll be surprised how much comes out, i reccomend using a shower head on a gentle setting and only as warm as you yourself would have and away you go You could use engine degreaser but you dont want to be too hard on the filter element itself as they arent super strong
