Overview

The ARM Motorsports F3X N55 Hose Upgrade is a high-temperature silicone hose kit designed to improve airflow in specific BMW N55 engines. It replaces OEM-style connections with a more secure hose-to-bead connection, reducing turbulence and potential leaks.

Constructed from 6-layer reinforced silicone, this hose is pressure-tested to withstand over 50psi, making it suitable for high boost applications. It features a 2.5" inside diameter and includes four constant-tension T-Bolt Clamps for a secure, long-lasting seal.
Show original supplier description
The ARM Motorsports F3X N55 Hose Upgrade is engineered to enhance airflow and reliability for BMW's N55 engines, specifically when used with ARM's FMIC Kit, Charge Pipe, and Turbo Outlet Pipe. This upgrade directly replaces problematic OEM-style connections, which are prone to leaks and can impede airflow, with a more robust hose-to-bead connection. By reducing the number of connections in the charge-air system from a typical ten down to just four, this hose kit minimizes turbulence and maximizes airflow efficiency. This streamlined approach not only improves performance but also ensures a leak-free seal, even under demanding conditions. The upgrade replaces sections of the turbo outlet pipe and charge pipe on both the hot and cold sides. Constructed from a durable 6-layer reinforced high-temperature silicone, these hoses are built to withstand the rigors of high boost applications, having been pressure-tested to over 50psi. The hoses feature a 2.5" inside diameter for optimal fitment and are secured by four constant-tension T-Bolt Clamps, which maintain their original torque specification over time, preventing loosening. This hose upgrade is designed for a range of BMW F22, F23, F30, F32, F33, F34, and F36 models equipped with the N55 3.0L engine. Fitment includes M235i, M235i xDrive, 335i, 335i xDrive, ActiveHybrid 3, 435i, and 435i xDrive variants across the specified chassis.
