About this product
The N54's factory intake manifold is plastic, and ARM Motorsports notes it becomes a bottleneck once a build passes roughly 400whp. ARM's mandrel bent T6061 aluminum manifold, with CNC machined connections, replaces it and supports 600+ whp and beyond when paired with port injection.
This is a direct-fit manifold: every factory connection carries over, with no cutting or fabrication required.
Important Compatibility Information
This manifold fits N54-powered BMWs. If your car uses the N55 instead, see the ARM N55 intake manifold.

Frequently Asked Questions
Why upgrade off the factory manifold?
The factory plastic manifold becomes a bottleneck past roughly 400whp; ARM's aluminum manifold supports 600+ whp and beyond with port injection.
Does this require cutting or fabrication?
No. It's a direct-fit swap that keeps every factory connection.
What if I'm not running port injection?
Block-off plugs for the port-injection ports are included.
Does this fit N55-powered cars?
No. N55 cars need a different ARM manifold, noted in the compatibility section above.
Should I pair this with other upgrades?
Yes, ARM's N54 charge pipe is a natural companion since the manifold keeps every existing connection.
