[QUOTE="RossKean, post: 1433073, member: 19880"] [U]Owner's manual says clean OR replace at the specified intervals.[/U] If a filter was uniformly dirty end-to-end, there is no doubt I would replace it but in my riding region, this is never the case. Most of the dirt blows out with compressed air, as per the owner's manual, and I don't worry about continuing to use it for far more than 12,000 miles. As long as "enough" air goes through the filter to keep the engine happy, the filter will actually stops a higher proportion of dirt (down to smaller particle sizes) as the openings become occluded with dirt. Of course, there is greater resistance to flow and eventually the engine will not be getting enough air. You will notice that typically one end of the filter is much worse than the other. This tells me that flow restriction is not yet severe and air still passes easily on a direct path - as it became restricted to flow, you would see more dirt on the other end as well. As you say, an air filter isn't that expensive and it isn't particularly difficult to change. Just saying it probably doesn't need to be changed as often if the environment is not especially dusty or high in pollen or other particulates. [/QUOTE]
