All else fails, buy some of these Uni foam filter sheets and make your own.  I prefer using the Uni foam filters over oiled gauze like K&N, Spectre, etc.  If you do this, you don't need to spend money on the pricey sticky Uni foam filter "oil".  Just get a can of regular cooking spray and use it.  Just make sure to rub the spray into the foam, let it sit for a few minutes, then tamp it down with a paper towel to remove any excess spray.  Works like a charm!
