PROFILE

The ARM N54 Intake Manifold is designed to support your high-horsepower N54 build!  The ARM N54 Intake Manifold allows more airflow over the OEM N54 intake manifold, supports port-injection, and is a bulletproof solution to the fragile plastic OEM N54 intake manifold.  



The factory N54 intake manifold was never designed to handle the demands of high-boost, high-horsepower builds. Its restrictive plastic design quickly becomes a bottleneck once you begin pushing your setup past the 400whp mark. The ARM N54 Intake Manifold replaces the weak plastic OEM N54 intake manifold with a durable, lightweight aluminum unit built to withstand extreme boost while dramatically improving airflow and increased fueling capability.

CONSTRUCTION

The ARM N54 Intake Manifold is a direct-fit and installs using all factory connections for a simple, OEM-style fitment. No cutting, no fabrication, and no tuning headaches.  You can use any existing components that are currently connected to your OEM N54 intake manifold, specifically any upgraded charge pipes.  

The ARM N54 Manifold expands both the airflow and fueling potential of your N54. Designed around smooth, high-flow runners and optimized plenum volume, it delivers increased airflow and improved efficiency across the powerband.  The larger, smoother runners improve top-end power and throttle response.




For N54 owners looking to step into higher power levels, the integrated top-mounted port injection bungs allow easy addition of a secondary fueling system. This provides the fuel volume required for full E85, methanol-free tuning, or big turbo upgrades, ensuring reliable performance at 600+whp and beyond.




For those not utilizing the port-injection system
, the ARM N54 Intake Manifold includes port-injection block-off plugs which allow the ARM Intake Manifold to support N54's without additional fueling.




With multiple expansion vacuum ports, you’ll have clean, easy access for connecting blow-off valves, boost gauges, Hobb’s switches, and other accessories without the need for drilling or T-fittings.




Constructed from high-strength T6061 aluminum, the ARM N54 Intake Manifold resists cracking, heat soak, and deformation even under extreme conditions, a massive reliability upgrade over the factory plastic piece.

SUPER great denim-should last for years!
Size: 30, Color: Truest Blue
lI don't know if these will be flattering on me, but I LOVE THEM. They're hip and cool and I will wear them although I am 65. Would look best with shorter shirts, but of course, not showing belly. A slim young woman would "kill" this look. Denim is heavy duty and all hardware top class. The ad said to size down, but I ordered my regular size. The waist is a little tight on me, but the barrel legs are loose and hang nicely. Definitely something I will wear with platform ankle boots or sneakers. I anticipate people will absolutely love them (younger folk) where people my age, may say hmmm because they are a statement piece.
