ARM Motorsports FMIC Hose Upgrade - BMW N54/N55 (E82, E90, E92, E93)

ARM Motorsports' Front Mount Intercooler Hose Upgrade replaces both the hot-side hose from the turbo outlet to the intercooler and the cold-side hose from the intercooler to the charge pipe with a single, extra-large 3-inch inside diameter design, about 50% larger than the factory intercooler hoses.

Each hose is molded as one piece rather than assembled from multiple sections, removing the connection points that create turbulence and restriction in a multi-piece hose setup.

Important Compatibility Information

This hose kit is built to connect an ARM front-mount intercooler to an ARM N54 or N55 charge pipe, and replaces the factory-length hot and cold side hoses. It requires a compatible ARM FMIC and charge pipe already installed. See ARM's 5" Front Mount Intercooler or 7" Front Mount Intercooler, along with the matching N54 charge pipe or N55 charge pipe.

Frequently Asked Questions

Will this work with my factory intercooler?
No. It's built to connect an ARM front-mount intercooler to an ARM charge pipe, replacing the factory hose routing entirely.

What boost level can this handle?
ARM tests this hose kit past 30psi, covering both stock-turbo N54/N55 cars and upgraded-turbo setups.

Is this one hose or two?
Two: a hot-side hose from the turbo outlet to the intercooler, and a cold-side hose from the intercooler to the charge pipe, each molded as a single piece.
