For sale are hidden storage cups for NAPA 4003 / WIX 10429 / WIX 24003 filters.  We've improved on the existing designs on the market by very slightly reducing the outside diameter of the cups which helps prevent jamming and makes removal from the filter much easier.  Please select the number of cups from the drop down.

Please make certain you are buying GENUINE 24003, 10429 or 4003 filters. There are many counterfeits available on eBay - these are not genuine and our cups are too large for the housings.

Please note that these adapters are strictly intended to be used for cleaning  or dry storage purposes only.  Any other utilization is to be regarded as misuse and is not supported, directed nor implied by NTC Trading Co.
