F3X N55 HOSE UPGRADE

The ARM F3X N55 Hose Upgrade works seamlessly with the ARM F3X FMIC Kit paired with the ARM N55 Charge Pipe and N55 Turbo Outlet Pipe. It improves airflow by eliminating the OEM-style connections between the FMIC, charge pipe and turbo outlet, and by reducing the overall number of charge-air transitions — converting leak-prone OEM connections to a secure hose-to-bead seal.

Highlights

• Eliminates OEM-style connections.
• Improves airflow.
• 6-layer reinforced high-temp silicone.
• Handles high boost with leak-free seals.

Construction

Cuts the charge-air connection count from the standard 10 down to 4 — fewer connections means less turbulence. It replaces the second half of the turbo outlet pipe plus the OEM connector and coupler on the hot side, and the OEM connector, coupler and lower charge-pipe section on the cold side. Built from 6-layer reinforced high-temperature silicone pressure-tested beyond 50 psi, sized to a 2.5" inside diameter, and secured with four constant-tension T-bolt clamps that won't loosen over time.
