ABSTRACT:
A supplemental cylindrical air cleaner or filter is provided for the inlet snorkel of a conventional automotive air cleaner housing and the supplemental air filter or cleaner incorporates a molded body of open cell material with said body including two elongated, upwardly opening semi-cylindrical halves including opposite side upper marginal edges with said halves disposed in side-by-side juxtaposed position with adjacent upper marginal edges of adjacent halves integrally formed and joined by a living hinge portion of said material extending therealong. The cylindrical halves include integral partitions or disks spaced therealong and projecting outwardly from the open sides of the halves with the partitions of one of the halves staggered relative to the partitions of the other half. The open sides of the halves are swung toward each other about the living hinge to form a peripherally continuous tubular member insertable into the aforementioned inlet snorkel with those portions of the partitions projecting outwardly of the open side of each half snugly received in and including marginal contours conforming to the inside cross sectional shape of the other half.
