A year ago I made the decision to just quit cleaning air filters. Since then I have never looked back. It may be the best thing I have ever done. It is almost as if I gave up some sort of addiction or vice. It makes me feel like the better person for doing so.
Okay, well it took a little while to get used to the idea of throwing away perfectly good filters. I kept collecting dirty ones until the pile was 20 deep. But then I just took the leap and sent them to be rubbish bin.
I go through enough filters that cleaning was always a dreaded chore. Plus, when I looked at the time, mess and cost of oil, shelling out about $12 for a new filter didn’t seem like such a bad deal.
After a year of use on all the test and rental bikes, I have just a couple of comments worth mentioning –
Overall the Maxima pre oiled filter seems to be good quality material and construction.
I am not completely convinced the filters come with enough oil for heavy use. So I spray just a little extra Maxima Fab 1 on each one when I install it. It doesn’t take much.
For the tour rental bikes, I was carrying a spare filter to change each after two days of riding. I would roll the filter like a cigar in its original bag to save space.
I have now changed that practice to using PC Racing Filter Skins over the filter. I find that I can typically run the skin for two days, then pull it for the next two. This saves me the hassle of carrying and changing filters on the trip. It also eliminates the possibility of getting dirt in the airbox while doing the filter change (typically after a couple of cold Tecates).
At $3 each, the disposable Filter Skins are even less expensive than having to do a filter change.
The Ready To Use Filter can be cleaned and reused. But for some reason they swell up like a balloon when doing so. But they will still work.
Using these methods, I feel the Maxima pre-oiled filter is giving me as much filtering protection as anything else available. It is a simple and economical solution to my particular needs.
I have also used the Twin Air Dust Cover extensively. It works good, but there are two draws backs. First, like a filter, it needs to be cleaned and oiled with each use. Second, I found that it would often concentrate air flow around the edges, where it does not seal tight. This would cause dirt to accumulate heavier at the edges and could lead to dirt penetration in those spots.
