The air cleaner assembly and systems also include a pulse tube extension coupled to the filter cartridge and extending into the cartridge passage along the longitudinal axis such that an outer tube surface of the pulse tube extension faces the inner filter surface of the filter cartridge. The pulse tube extension defines a tube passage located within the cartridge passage.
