ARM Motorsports N54/N55 5" AND 7" FMIC HOSE UPGRADE

The ARM Motorsports FMIC Hose Upgrade is the ultimate solution for improving airflow and turbo spool in your BMW 135i or 335i, particularly when paired with the ARM 5" or 7" Front Mount Intercooler (FMIC). This upgrade eliminates any restrictions in the OEM hoses by replacing both the hot-side hose (turbo to intercooler) and the cold-side hose (intercooler to charge pipe). With an inside diameter of 3", these hoses are 50% larger than the OEM hoses, making them the largest available for the E8X and E9X chassis.

Constructed from five layers of high-temperature silicone, the ARM FMIC Hose Upgrade can withstand up to 30psi, making it perfect for both stock turbo applications at 22psi and upgraded turbo setups running up to 27psi. The single-piece construction on both hoses ensures smoother airflow, reducing turbulence caused by multiple connections. This feature, combined with the ARM N54/N55 Charge Pipe Upgrade, provides your BMW with a full 3" piping system from the intercooler to the throttle body, significantly improving air flow and throttle response.

The hot-side hose measures 2.5" to match the OEM turbo outlet and expands to 3.25" ID for the ARM FMIC. The cold-side hose maintains a 3.25" ID at the intercooler, reducing slightly to 3" all the way to the charge pipe. This upgrade offers a more efficient path for the charged air, with fewer connections, ensuring the best possible flow for your N54 or N55-powered BMW.
