Abstract: A hollow intake manifold-type body is provided for mounting between the cylinder banks of a V-type engine and the hollow body defines a vertically oriented inlet passage, a horizontally enlarged lower chamber into whose upper central portion the lower end of said intake passage opens, a horizontal baffle disposed in and dividing the lower chamber into upper and lower chamber sections communicated with each other in corresponding outer peripheral zones thereof spaced outwardly of the baffle, a vertically oriented outlet passage whose lower end opens downwardly through a central portion of the baffle and an upper chamber above the lower chamber and vertically through which the inlet passage extends.
