VRSF HD intercooler, BMW X3/X4 35i and 40i, F25/F26 (N55)

VRSF intercooler kits for high power BMW’s.

BMW intercooler (FMIC)
In BMW turbo engine, like in all turbo engines the intake air temperature is absolutely significant. With every degree up or down, you will lose or gain that previous horsepower. Hot air is less dense and oxygen rich by nature (resulting in less power output), but in addition to that your Engine Control Unit will actively limit the engine power whenever the IAT shows any signs of rising.

Therefore a high performance intercooler is always a beneficial upgrade, even in stock engine.

VRSF intercoolers are designed specifically for each BMW model and engine to offer an efficient solution.

Intercooler for BMW X3 35i, X4 35i and X4 40i models with N55 engines

This intercooler kit fits in listed models with N55 3.0L engine. Superior cooling effect compared to stock intercooler, while with OEM core the intake air temperature typically rises during longer acceleration, with VRSF core the IAT often actually drops during 3-4 gear pull. Quick and easy bolt-on fitment.

Intercooler core and construction

OEM BMW tube and fin intercooler is designed to support low boost levels and air flow. However, once boost levels and air flow are increased, the OEM unit simply can not keep up with the cooling demands any more.

VRSF core comes with high density bar-and-plate design to allow efficient temperature reduction with minimal pressure drop. Intercooler is specifically designed for upgraded turbo cars running larger turbos and higher boost pressures. Core features a cast aluminum end tanks for improved flow and durability.

Installation

All needed accessories are included, to make installation possible even in home garage if you will. Normal tools and equipment with some extra time should be enough.

This kit doesn’t need modifications for bumper or structures.

Depending on your trim level and model, it’s always good to be prepared for some minor trimming or honing for that perfect fitment.
