BMW GEN2 B58 INTAKE MANIFOLD w/ PORT INJECTION

Bigger Plenum. Smoother Airflow. More Power Potential.

The enlarged plenum increases the volume of air available to the engine while helping reduce restriction through the intake manifold. Air enters through the throttle body, fills the high-volume plenum, and is distributed across all six cylinders.

The larger internal volume is designed to provide:

• Increased airflow capacity
• Smoother air distribution across all six cylinders
• Improved throttle-response potential
• Better charge-air cooling
• More consistent intake-air temperatures during repeated pulls
• Greater horsepower and torque potential
• Improved support for upgraded turbos and high-boost applications

The Gen 2 B58 uses a water-cooled charge-air cooler integrated into the intake-manifold assembly, making the manifold and cooler core critical components in controlling charge-air temperature and airflow.

Integrated Port Injection

The Project Gamma manifold includes six dedicated port-injection provisions, allowing one supplemental fuel injector to be positioned for each cylinder.

Port injection can provide the additional fueling capacity required for vehicles running:

• Upgraded turbochargers
• Higher boost pressure
• Ethanol-based fuel blends
• High-horsepower custom tuning
• Drag, roll-racing and track applications

A correctly configured port-injection system can supplement the factory direct-injection system when additional fuel delivery is required.

Three Auxiliary Injection Ports

The manifold also features three auxiliary ports that can be used for properly configured methanol-injection or other advanced fueling applications. This gives tuners greater flexibility when building a complete fueling and charge-cooling system.
