The Gates valve cover-to-intake tube emission control hose for 2002–2009 Chevrolet Trailblazer 6‑cyl 4.2L links the valve cover to the intake tube as part of the emissions plumbing. It restores the factory path for crankcase vapors on compatible Trailblazer models and helps maintain proper engine ventilation and emissions control where the original hose is damaged.
