Why Replace This Part?
Water drain valves can harden, crack, perish, block, or go missing due to age, heat, dirt, oil vapour, and previous air filter housing work. A faulty or missing valve may allow moisture to collect in the housing, cause poor sealing, or leave the intake system incomplete. Replacing the valve helps restore correct drainage and original-style air box detail.
