|Cold Air Intake Bypass Valve Filter|
Cold air intake bypass valve filter helps your engine intake to have consistent air flow and prevent hydraulic-lock. Many cases driving under heavy rain or wet floor, aftermarket cold air intake will often absorb the moist into the filter, having it unable to have air flow.
The bypass helps resolve that problem, by having a second air filters. This secondary filter will prevent water from going into the intake causing damage to the engine.
