That happens to the cocksport I take too. You can get a little hydrophobic cover from ebay that will also help keep larger debris (leaf fragments bugs) from getting stuck in the pleats.
Like this, available different sized.
Universal, fits most cone and cylinder shaped filters from 4.75" to 5.25" wide x 5.25" to 5.75" High. Most affordable cold air and short ram pre-filter on the market. It repels large sprays of water, but it is NOT watertight.
