The Gates valve cover-to-air cleaner emission control hose for 2016–2020 Honda Civic 2.0L connects the valve cover to the air cleaner inlet as part of the emissions system. This hose preserves the intended routing for crankcase vapors on supported Civic models and supports correct ventilation and emissions plumbing when the original hose is compromised.
