The ARM Motorsports' 7.5" FMIC Hose Upgrade is designed to work seamlessly with the ARM 7.5" FMIC and ARM N54/N55 Charge Pipe upgrades to improve airflow over the OEM piping. The ARM Motorsports' 7.5" FMIC Hose Upgrade replaces the short hose from the turbo outlet pipe to the intercooler on the hot side, and the longer hose from the intercooler to the charge pipe on the cold side. With it's extra-large 3 in inside diameter, the ARM intercooler hoses are 50% larger than the OEM intercooler hoses, the largest intercooler hose upgrade available for the E8X and E9X chassis.
