The pleated filter element includes a filter medium and at least a first perforated support member, the filter medium being disposed adjacent to the perforated filter support member. The filter medium includes a portion extending beyond the perforated support member comprising a seal that prevents or reduces bypass of unfiltered exhaust gas around the pleated filter element. |
