Take your BMW S58 engine to the next level with the Project Gamma S58 Intake Manifold with Port Injection, engineered for enthusiasts and professional builders looking to maximize airflow, cooling efficiency, and fueling capacity.

Designed as a direct replacement for the factory plastic intake manifold, this premium cast aluminum manifold features a significantly larger integrated water-to-air intercooler core and built-in top-mount port injection provisions, making it the ideal upgrade for high-boost, ethanol, race fuel, and big turbo applications.

Whether you're building a 900+ horsepower street car or a dedicated race vehicle, the Project Gamma S58 Intake Manifold delivers the airflow, cooling, and fueling capability needed to support your performance goals.

 

Why Upgrade Your Factory S58 Intake Manifold?

The factory S58 intake manifold works well for stock power levels but quickly becomes a restriction as horsepower increases.

The Project Gamma manifold solves these limitations by offering:

• Significantly increased airflow
• Much larger integrated intercooler core
• Integrated port injection system
• Superior heat management
• Strong cast aluminum construction
• Excellent reliability under a big boost

The result is lower intake air temperatures, improved throttle response, greater fueling capacity, and more consistent horsepower during repeated pulls or track use.

 

Massive Integrated Intercooler Upgrade

Cooling plays a critical role in maintaining power on turbocharged engines.

The Project Gamma manifold incorporates a 20% large bar-and-plate water-to-air intercooler core that dramatically increases cooling efficiency over the OEM unit.

Injectors and controller not included.
