AMS Performance BMW B58 Intake Manifold (Part No. AMS.51.08.0001-1)

If you're pushing the limits of your BMW M340i's performance, you know how crucial it is to keep those intake temperatures in check. The AMS Performance BMW B58 Intake Manifold is designed specifically for the B58 3.0L Turbo engine found in the 2019 and newer M340i (G20 and G21 chassis). This manifold is engineered to enhance your vehicle's cooling efficiency and fuel delivery, ensuring that your engine performs at its best, even under heavy load.

Why Choose the AMS B58 Intake Manifold?

As horsepower numbers climb, so do the demands on your intercooling system. The AMS Performance intake manifold features a unique parallel twin core design that optimizes coolant flow, providing superior heat exchange compared to stock options. This means cooler, denser air entering your combustion chamber, which translates to better performance.

Additionally, the manifold is equipped with a flush-mounted -8AN fuel rail that allows for auxiliary port fuel injection. This design ensures that atomized fuel travels smoothly to the combustion chamber, maximizing efficiency and power output.

Features

  • 1250+ HP rated parallel air-to-water intercooler cores for exceptional cooling performance
  • Auxiliary port fuel rail with -8AN side ports for increased fueling options
  • Computational fluid dynamics (CFD) verified design for optimal airflow distribution
  • Angled port injection for enhanced fuel atomization
  • 135% larger core area compared to OEM for improved heat dissipation
  • Three extra -4AN orb ports on the plenum for additional vacuum source points
  • Includes all necessary components: hardware, lines, and fittings for a straightforward installation
