The ARM Motorsports F3X N55 Hose Upgrade is designed to work seamlessly for the ARM F3X FMIC Kit paired with ARM N55 Charge Pipe and ARM N55 Turbo Outlet Pipe upgrades.
The ARM N55 Hose Upgrade is used to improve airflow by eliminating the OEM style connections from the FMIC to the Charge Pipe and Turbo Outlet Pipe, and reducing the overall amount of transitions of the charge-air. The OEM style connections are prone to leaking and can be difficult to connect properly. The ARM F3X Hose Upgrade converts the OEM style connections to a more secure hose-to-bead connection for a leak-free seal.
The ARM F3X N55 Hose Upgrade reduces the overall amount of connections needed for the charge-air piping to only 4, as opposed to the standard 10. This is beneficial because each connection can create turbulence in airflow, therefore the less connections you have in your charge-air system, the less opportunities for turbulence in your N55's charge-air.
The ARM F3X N55 Hose Upgrade replaces the second half of the turbo outlet pipe and OEM connector and coupler on the hot side. On the cold side it also replaces the OEM connector and coupler, along with the lower section of the charge pipe.
Below you can see how the ARM Hose Upgrade reduces the connections on this N55 RWD Charge Pipe Setup from 5 to only 2, eliminating 3 or 60% of the connections from the standard setup.
Similarly, the ARM Hose Upgrade reduces the connections on this N55 Turbo Outlet Pipe setup from 5 to 2 as well. The removal of these extra connections improves airflow by reducing turbulence.
The ARM F3X N55 Hose Upgrade utilizes 6 layer reinforced high-temperature silicone for durability and to maintain its structure for high boost applications. Our silicone hoses have been pressure tested to withstand over 50psi, enough for even the most demanding N55 builds.
Each hose is sized to 2.5" inside diameter to allow for proper fitment to the ARM N55 Turbo Outlet Pipe and Turbo Outlet Pipe. To secure the N55 Hose Upgrade are four constant-tension T-Bolt Clamps. These clamps will not loosen over time and ensure that they keep the original torque spec that you tighten them to.
