Show original supplier description
The ARM Motorsports 1K FMIC is an upgrade front mount intercooler designed to significantly enhance the cooling performance of E-Series BMW models. Constructed with a substantial core volume of 1,155 cubic inches, the intercooler measures 20"x11"x7.5", making it 270% larger than the factory unit. This oversized core is paired with an ultra-dense fin pack, featuring 20 fins per inch, to maximize heat dissipation and maintain consistent intake air temperatures even under demanding conditions. The intercooler is engineered to support vehicles with upgraded twin turbo and big single turbo setups, with a capability of handling over 1,000 wheel horsepower. The end-tanks are meticulously designed with smooth transitions and integrated cast fins at the inlet port to ensure uniform charge air distribution and minimize turbulence. The 3-inch inlet and outlet ports are optimized for fluid transitions, further reducing air resistance and improving overall airflow efficiency from the turbos to the charge pipe. This intercooler is specifically designed for a range of BMW E82/E88 1 Series and E9X 3 Series models equipped with N54 or N55 3.0L engines. Fitment includes the 135i, 1M, 335is, 335i, and 335xi, with specific model year ranges noted for compatibility. An optional lower charge pipe upgrade is available to complement the intercooler's performance.
