Description
The ARM Motorsports FMIC Hose Upgrade is engineered to eliminate restrictions in your BMW’s intercooler system by replacing the factory piping with oversized, high-flow silicone hoses. Designed specifically for use with the ARM 5" and 7" FMIC and ARM N54/N55 Charge Pipe upgrades, this kit ensures optimal performance gains by improving turbo spool, airflow, and throttle response.
This hose upgrade includes a hot-side hose that connects the turbo outlet to the intercooler, and a cold-side hose that connects the intercooler to the charge pipe. Featuring a massive 3" internal diameter, these hoses are 50% larger than stock, making them the largest available for the BMW E8X and E9X platforms.
Key Features
- Direct-fit replacement for OEM hoses (no trimming or modification required)
- Single-piece design for both hot and cold sides to reduce turbulence
- 5-ply high-temperature silicone construction
- Supports boost levels over 30psi
- Designed to work exclusively with ARM 5" or 7" FMIC and ARM N54/N55 Charge Pipes
Technical Specs
