Bros, Quick Information Sharing about 9th Gen Civic; (As got from 3S Service Shop)
9th gen uses wet type element in its air cleaner so dont use blower to clean its element filter as existing dust/dirt may stuck in even more. First of all, unlike dry type filter, it is not needed to clean filter 10k Kms (Total life time), but in case you drive in dusty roads then just get filter out and gently bang it against floor to drop wet dirt off.
Be aware some time over efficient service station guys after servicing car just remove filter and clean them with compressed air as a courtesy to owners.
