Abstract: This invention comprises an Air filter element frame for the internal combustion engine of seal comprising a compressible seal or compressible gasket; illustrated by a polyurethane foam seal/gasket; and a process of making the illustrative seal/gasket wherein two parts of a mould provide a channel around the four margins of the air filter elements that have Guide Slots and molten polyurethane mixture is filled up, entrained with air bubbles and the compressible seal is formed around the margins. The Air filter element frame made of thermoplastic material combined with additives comprises an air filter element frame holding feature, filter paper media, a Guide Slot provided on all the four margins holding the polyurethane foam seal/gasket that facilitates assembly by press fitting. The filter paper media used are insert molded into the air filter element frame.
