The ARB 170112 kit routes up to four assembly vents to a single elevated filtration point, delivering zero back pressure and zero vacuum performance so your oils stay clean and your seals aren’t stressed during off‑road crossings or deep water drives.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the ARB breather kit prevent water from entering drivetrain components?\u003c\/h3\u003e\n\n\u003cp\u003eThe kit uses a raised air filter and a small manifold so vent lines terminate high on the vehicle, above likely waterline exposure.
