do88 15-20 BMW M3/M4 (F8X) BigPack Intercooler Kit w/Intercooler + Radiators

The core of this intercooler kit is its massive 1030 x 240 x 120 mm intercooler, featuring a 60 mm thick core. This substantial size is designed to significantly increase the cooling surface area compared to the stock unit, which is crucial for managing the heat generated by the twin-turbocharged S55 engine found in the 2015-2020 BMW M3 and M4 (F8X chassis). By lowering intake air temperatures, this kit helps the engine produce more consistent power, especially under demanding conditions or after modifications.

Beyond the main intercooler, this BigPack kit also includes two high-performance radiators, one for engine coolant and another for the power steering fluid. These radiators are engineered to provide improved cooling capacity, ensuring that vital systems stay within optimal operating temperatures. The kit utilizes custom-made silicone hoses with integrated silicone reinforcement, designed to withstand higher boost pressures without collapsing. All the necessary mounting hardware and detailed installation instructions are included, making it a comprehensive solution for enthusiasts looking to enhance their vehicle's forced induction system.

This kit is a substantial upgrade for the F8X M3/M4, aimed at drivers who push their vehicles hard or have made performance modifications. The increased cooling efficiency can lead to more reliable power delivery and help prevent heat soak, which can otherwise reduce performance. While this kit is not CARB approved and cannot be shipped to California, it represents a well-built solution for improving the thermal management of your M3 or M4.
