Filters????

[92bonny]

Hello everyone,
A friend of mine owns a 1991 sc400 (Australian version) and needed a new filter for, what I was told, a Pollen Air-conditioning filter. He also gave me the part number which is 88508-24010, but so far I have been unable to locate one in the states, they are extremely expensive from Australia so I was wondering if anyone knew where to get the filters cheaper in the states and if the cars in the U.S. even have the filter. Any help would be much appreciated. Thanks.
