Built in a deep black finish, it slips into a 1\/2\" hose or port and helps direct blow-by and crankcase ventilation away from sensitive parts and intake openings. Its low-profile design and robust construction offer a maintenance-friendly component that integrates with foam filters wetted with sticky oil to trap dirt, dust, and mud.\n\n\u003ch3\u003eHow does this breather protect my ATV’s engine?\u003c\/h3\u003e\n\u003cp\u003eThe breather provides a controlled outlet for crankcase gases, reducing pressure build-up and preventing contaminants from being drawn into the intake.
