so my cousin-in-law has a K&N installed on his caburated B13, and as expectied it got dirty after a while, so he asked me what to do, so i told him to buy the recharger kit, but he said that he dosent have the time nor the money at the time so he'll leave it there. now one afternoon he tells me that the filter has gotten really dirty, and that he used an air intake cleaner(those gasoline based aerosol cleaner) on the filter and all the black muck came off. by this time i'm really dissapointed cuz i know that this shouldnt be done and i tell him again that he should buy the filter recharger. but he dosent listen to good advice and then re-installs it.(about 3 months ago)
now a couple days ago i bought a recharger kit for the first time to clean my dirty K&N filter, and he asked me to clean his. so i sprayed on the cleaner, washed it out let it dry then applied the filter oil and left it overnight to dry the result:
the filter is now completely ruined, it does not look pink as it should but still looks white, its not that i didnt apply enough oil but that, buy him cleaning his filter with the cleaner and
not re-oiling the filter, the filter medium (cotton) has absorbed a lot of dust particles, making it look white/grey in colour.
the filter is now useless and would not filter anything since K&N relies on the oil to trap dust and not the cotton itself.
ppl plz dont make this mistake
