      Description

      Engine Warm-Up Control. The Exhaust Manifold Heat Riser Valve accelerates the warming of a cold engine by regulating exhaust flow between the manifold and the head pipe. This improves engine efficiency and reduces emissions during initial start-up. Proper operation of this valve helps prevent power loss and protects the exhaust manifold from damage caused by a stuck or faulty valve.
