The ARM N54 Inlet Adapters give you the ability to use 2" N54 Inlets on your stock N54 turbos. The ARM N54 Inlet Adapters are the perfect solution if you want to upgrade your inlets while running the OEM N54 turbos, but are planning on installing upgraded turbos in the future. This will save you the expense of having to purchase two separate sets of inlets, one for the stock turbos and one for the upgraded turbos.

The ARM N54 Inlet Adapters are constructed of CNC machined T6061 aluminum. They have a 2" outside diameter on one end to properly fit 2" N54 Inlets, and a 1.75" inside diameter on the opposite end to mate up to the stock N54 turbos. The 1.75" end has been machined to accommodate an O-ring to create a tight seal at the turbo and prevent any air leaks.
