Abstract: A filter cartridge for use in separating a hydrophobic liquid aerosol phase from a gas stream, as a crankcase ventilation filter for example, is described. The cartridge includes a media pack comprising filtration media surrounding an open interior and a first end piece. Various structure included on the first end piece is described. An example is a D-shaped projection. Also described is an assembly including the filter cartridge, specific features of a housing component of the assembly. Methods of assembly and use are also described.

Abstract: A heating device for use in an internal combustion engine for heating the air entering the cylinder head from the intake manifold. The heating device includes a frame having a body defining an air intake opening and a hanger extending from the body. The heating device further includes a first resistance ribbon and a terminal assembly coupled to the frame, electrically connected to the first resistance ribbon and electrically connectable with a power source. Finally, the heating device includes securing means for coupling the first resistance ribbon to the hanger in a vertical orientation.
