Performance airfilters for a Dakar?

Somehow.(Not somehow - it was that moerse puddle) I managed to get my air filter wet last week saturday at the sand riding. Unknown to me!
On Friday last week I noticed a difference in the engine noise when accelerating. And also much better performance in general except a dead spot at very low revs. (When blipping the throttle from idle)

Had a hunch and opened the airbox - My filter is somewhat holey!!!!

Riding without a filter is obviously out of the question, so where can I get a filter that lets through more air?? Are there any available in SA, or do I have to go the online shopping/mail order route?
The difference in the bikes performance is just too big to ignore!
