This is Precision Raceworks 601-0121-b N54 Forward Facing Manifold **B-Stock**.

N54 PERFORMANCE FORWARD FACING INTAKE MANIFOLD is designed to work with both 335i and 135i BMW's that came with N54 engines.  This is a perfect way to add reliability while increasing air flow, adding port injection.  Best of all our kit comes with ports to add direct port meth or direct port nitrous!

Please Note: For the B-Stock manifold, during manufacturing the flange was welded at an incorrect angle, and as a result, the included spacer/adapter plate is REQUIRED. Additionally, these may be incompatible with phenolic spacers.

 

  • Increased Airflow
  • Center flow port injection (fits all brand injectors)
  • Stronger than stock plastic manifold
  • Multiple expansion ports for larger BOV line, Boost Gauge, etc
  • Proprietary machining allows our manifold to use OEM o-rings (included)
  • Less heat soak than most other aftermarket aluminum manifolds means proven lower IAT's

Required Fueling option(s)

  • Pack of 6 Genuine Bosch Motorsports injectors
    • Flow matched to the highest standards (certs included)
    • Full stainless wetted internals for corrosion resistance
    • Individually serialized for full injector flow and resistance report (included)
    • 750cc at 3bar , 900cc at 4bar , 1050cc at 5 bar ( advertised at 750cc by industry standards)
  • Performance Fuel Line
    • Features Aeroquip AN6 Socketless fuel hose
    • All fittings CNC machined from 6061 aluminum
    • Anodized finish to withstand all fuel types (including e85)
    • Female fitting features dual seals to ensure a zero leak connection to HPFP

Other Requirements:

  • Relocated inlets or Single Turbo
  • Port Injection Controller
    • AIC-1 - The basic injector controller used for years.  This controller is easy to tune, and utilizes batch firing (all injectors fire at the same time)
    • ReFlex Lite - Simple controller that is similar to the AIC in price, but gives you Seqential fire of your injectors.  This improves fuel trims, fuel pressures are more stable, and each injector will output more fuel each time it fires.
    • ReFlex Plus - Advanced controller featuring CanBus integration for most F-series cars, ability to add an ethanol sensor and integrate a true flex fuel tune, ability to add a fuel pressure sensor, and additional capabilites.
  • Custom Tune for Port Injection
    • You will need a custom tune from the tuner of your choice to maximize the output and drivability once adding port injection

 

The use of this manifold requires the extension of two harnesses

  • The T-Map sensor - We offer the 3.5 Bar t-map extension harness for this purpose.
  • Throttle Body harness - There are no extension harnesses for this, you must cut and splice in additional wire to extend this harness.


This high quality solution is direct plug and play replacement for the factory intake manifold on all N54 cars.  With the OEM like fitment and the ability to run any fuel or combination of fuels the BMP intake manifold is the right solution for all build levels!
