Motosport gave excellent service....easy to order, arrived on time, prefilter was as advertised....perfect fit, very sensible addition to the OEM air filter....thanks guys...I have placed a second order....
Keeps air filter clean longer and much easier to clean than actual filter. I did not notice any power loss but I'm no expert. I did find it be a pain to squeeze into air box on my 2012 ktm, but not that big of a deal. I only use on real dusty weekend trips to keep from having to clean air filter which I hate doing.
i was getting a little bit of fine dust through air filter out in the desert and put this on and seems to help. can't feel any difference in power. if it protects the engine just a little for $20, i am all for it
If I ride both days on the weekend this cover is perfect. I oil the filter and cover and take the cover off after the first day. The filter underneath is perfectly clean and I'm ready to go. Really easy to put on and take off.
They do tear up faster than a filter, but overall hold up well and certainly do their job.
If anyone hates cleaning filters as much as I do, this is a go. It extended my filter cleaning by one ride, which to me is killer. There is, however a slight reduction in power. I personally don't think it is anywhere near enough to win or lose a race; as ability and stamina are much more important. Def needs to be oiled, as I tried without oiling it and dirt comes thru...
I bought on the recommendation of a friend who was having the same problem I was with super fine dust getting by the filter. WIth this extra layer of protection over the original filter I have been able to virtually eliminate the fine dust problem. Plus it makes cleaning the underlying filter easier since most of the heavy stuff gets caught by the dust cover. I only wish I had ordered one long ago!
Sure, this could be washed and re-used. Keep in mind though, this is made of coarse foam and smaller particles will lodge themselves in the pre-filter and may be need to be cleaned carefully, or you'll risk the chance of tearing the foam.
