Walker White Outerwear - Round 14" Filter H774009L An external water bypass bossSpecifically designed Outer wears for Walker Performance Filtration. These white outer wears help distinguish the good from the bad. They let you see when the element needs cleaned and replaced much sooner than the colored versions. They let you see the hood angles easier as well. We make them baggy on the filters so the oils from the media don't create any restriction to the air filter.
