The 6B31 features an aluminum variable intake manifold that uses a resin-made 2-stage Induction Control Valve to provide the benefits of short and long intake tracts, automatically switching in response to engine speed. A flap inside the Induction Control Valve remains closed below 3,600 rpm, forcing the intake charge to take a longer route to the inlet valves. Over 3,600 rpm, the flap opens, providing a shorter tract to the valves to increase power.
