Abstract: A high performance automotive air filter is produced by injection molding a base piece and a cap piece, applying a layer of adhesive to the base and cap pieces, placing the base and cap pieces on the bottom and top edges of the air filter medium, and curing the adhesive layers to adhere the base and cap to the filter media.

Abstract: Protective covers for cab guards or racks which extend vertically from the front rail of a truck bed behind the rear window of the truck cab are disclosed. The protective covers may be molded to fit any shape or size of truck bed rack. In one embodiment, the protective cover includes a generally horizontal top section which extends to two generally vertical side sections. Additional sections are typically provided between the side sections to provide a barrier that protects the rear window of the truck cab. When the protective cover is installed, it covers most of the surfaces of the truck bed rack, except the forward-facing surface of the rack located adjacent to the truck cab. Thus, the protective cover provides protection to essentially all exposed surfaces of the truck bed rack, while allowing easy installation.
