A friend of mine just moved back in town from up north. He is selling his VW and has sold some of the maintenance items he's bought over the years. He has three Premium Guard PA4622 that fit my Passat. He just gave them to me. After looking these up, they have the pre-filter felt type foam material I've always seen named as a "winter or anti-condensation" filter. These ok to use in warm climate? PG website just lists it as the filter for my car without caveat.
