To compensate to the lowered air pace, the main-technology engines bundled the T-VIS element, where twin intake runners are fitted with butterfly valves that opened at close to 4,200 rpm. The outcome is the fact at decreased rpm (when the airspeed would normally be slow) four in the 8 runners are shut, which forces the engine to draw in all its air as a result of half the runners in the manifold.
