Hi all,
Just cleaned my K&N filter yesterday and had re-oiled the dirty side of the filter. But do not know if the clean side have to be oiled as well. Had heard bad response to over oiling of the filter but also knew that the K&N filter does not filter properly if it is not oiled. So need advice from more experience bros on whether need to oil both sides of the filter. The instructions with the box never say about this. Thanks.
