N54 INLETS
The ARM N54 Inlets are the ultimate relocated inlet system for your N54 — freeing up to 60 whp / 60 wtq, with faster turbo spool, quicker peak boost and more turbo volume. If you're maxing out stock or upgraded twin turbos, these are a must.
The stock N54 inlets are narrow and flat, choking airflow to the turbos and limiting how fast they spool and hit boost. ARM relocates the filters from the driver's side to the passenger side, dramatically shortening the path intake air has to travel.
Highlights
- Gains of up to +60 whp / +60 wtq.
- Faster turbo spool and increased turbo volume.
Construction
- High-temperature steel-reinforced silicone relocated inlets.
- Manifold heat shield and air-filter heat shield keep turbo heat away from the filters.
- Filter bracket and boost-solenoid bracket lock everything in place under hard driving.
- Includes coolant and power-steering reservoir relocation brackets for an easier install.
