Abstract

An internal combustion engine includes a blower housing and a filtration system positioned in a path of cooling air from the blower housing. The filtration system includes a filter housing comprising a base that defines a series of radially extending fins extending circumferentially around the base, and a filter cartridge defining a longitudinal axis and being removably arranged within the filter housing. The base includes a drain and a channel formed radially between a first raised surface and a second raised surface, and the drain is in fluid communication with the channel. The filter cartridge includes a bottom endplate in engagement with both the first raised surface and the second raised surface so that fluid flow is inhibited through the channel and to the drain, and a filter media extending axially from the bottom endplate.
