Engine assembly having a baffle in the intake manifold

A vehicle comprising:

• an engine including a first cylinder bank and a second cylinder bank, the first cylinder bank including a first pair of adjacent firing cylinders, the engine being configured to fire the first pair of adjacent firing cylinders in succession, the second cylinder bank including a second pair of adjacent firing cylinders, the engine being configured to fire the second pair of adjacent firing cylinders in succession, wherein the first pair of adjacent firing cylinders refers to two of a plurality of first cylinders in the first cylinder bank that are adjacent to each other, fire consecutively, and have a minimum crank angle spacing therebetween with respect to the rest of the plurality of first cylinders, and the second pair of adjacent firing cylinders refers to two of a plurality of second cylinders in the second cylinder bank that are adjacent to each other, fire consecutively, and have a minimum crank angle spacing therebetween with respect to the rest of the plurality of second cylinders;
• an intake assembly including an intake manifold, the intake manifold including a plenum, the plenum defining a first pair of ports and a second pair of ports, the intake manifold defining an inner manifold cavity, the inner manifold cavity being in fluid communication with each port of the first pair of ports and the second pair of ports, each port of the first pair of ports being disposed in fluid communication with one of the first pair of cylinders, each port of the second pair of ports being in fluid communication with one of the second pair of cylinders;
• and
• wherein the intake assembly further includes first and second baffles disposed within the intake manifold, each of the first and second baffles protruding directly from the plenum into and toward the inner manifold cavity, the first baffle is disposed only between the first pair of ports, and the second baffle is disposed only between the second pair of ports, the first and second baffles collectively including all the baffles inside the intake manifold;
• wherein the plenum is elongated along a manifold axis, the first baffle extends from the plenum, the first baffle is elongated along a baffle axis, and the baffle axis is substantially perpendicular to the manifold axis;
• and
• wherein all the baffles inside the intake manifold are disposed within the inner manifold cavity between the first and second pairs of ports.

A method of manufacturing an engine assembly, comprising:
