A tuned intake manifold is provided for OTTO cycle engines and includes a plenum having an aperture through which a gaseous fuel mixture can be received. First and second branch openings are disposed at opposite points across the plenum, with respective first and second branch conduits connected thereto. Each branch conduit divides into a plurality of runner conduits all terminating at a head flange. The various gaseous paths, each defined by one of the branch conduits and one of the runner conduits, have substantially the same length, substantially the same volume, and substantially the same radius and arc-length of curvature.

A tuned intake manifold for Otto cycle engines, comprising: a plenum, an aperture in the plenum through which the plenum can receive a gaseous fuel mixture, first and second branch openings into the plenum, the openings being disposed in substantial opposition to each other across the plenum, first and second branch conduits communicating with said first and second branch openings respectively, each branch conduit divaricating into a plurality of runner conduits all of which terminate at their connections to a head flange; all of the various gaseous paths, each defined by one of the branch conduits and one of the runner conduits into which the branch conduits divaricates, being substantially free of abrupt angulations; and all said paths having substantially the same length beginning at the plenum, substantially the same volume, and substantially the same radius and arc-length of curvature.
