An engine includes a cylinder block defining a bank of cylinders having physically adjacent first and second cylinders. The engine also has a gas compressor configured to pressurize an ambient airflow for delivery to the first cylinder and the second cylinder. The engine additionally has intake valves configured to control delivery of the pressurized airflow as a first airstream to the first cylinder and a second airstream to the second cylinder for combustion therein. A firing interval for the two adjacent cylinders results in the first airstream temporally overlapping the second airstream. A charge-air cooler is configured to cool the pressurized airflow prior to delivery thereof to the first and second cylinders and includes a cold-side plenum for discharging the pressurized airflow toward the first and second cylinders. A partition in the cold-side plenum is configured to separate the first airstream from the second airstream and thereby minimize interference therebetween.
