Abstract
An improved induction system for a V type engine having angularly disposed cylinder banks that is comprised of a pair of plenum chambers that are disposed in side by side relationship between the cylinder banks. Intake passages extend at right angles from each plenum chamber through the other plenum chamber and serve an intake port of the opposed cylinder bank. The plenum chambers are staggered relative to each other so as to provide a void at one end of the engine in which an accessory is positioned. An intake device supplies air to the plenum chambers and it extends beneath them and is connected by fasteners which are accessible through removable covers of each of the plenum chambers.
