Twin air filter dust cover on a TE510?

Hey guys - does anyone know which Twin Air air filter dust cover (if any) fits the filter that comes with the 2008 TE510? We're headed to Moab in a few months and I'd like to have something in case it's super dusty ...

Thanks in advance,
Jeff

we aussies (well i live here anyway) use swimming pool filter skins... they pikc up all the crap dust here and thats superfine... just pull it over the filter... we buy 5 of them for 7 bucks ! work a treat.. you can remove and refit new in 10 mins..

Some Aussies are also known to use their girlfriends stockings, which work brilliantly and can be doubled over on themselves to increase filtration ability ... I swear by it.

I use the left over 08'+ ktm hard parts dust covers from when I had 5 orange bikes in my garage
