Heat Riser: A channel in an intake manifold through which exhaust gas flows in order to heat the manifold, thus aiding in fuel vaporization.
Heat Riser Valve: A control valve between the exhaust manifold and exhaust pipe that restricts the flow of exhaust, causing it to flow back through the heat-riser channel under the intake manifold. It acts as an aid to fuel evaporation and to speed engine.
