BigPack BMW F8X M3 M4, Intercooler + Pipes + Radiators

This is our different BigPack configurations for the BMW M2C / M3 / M4 F8X
These are complete packages for the charge air cooling system with drop-in-fitment!

The S55 turbo engine that powers the BMW M2C / M3 / M4 F8X uses a Top mounted water-cooled intercooler instead of an “regular” air-cooled intercooler. The stock top mounted intercooler has a Tube&Fin core with clamped plastic end tanks. This construction has its drawbacks since it is prone to crack and start leaking coolant into engine or leaking boost pressure out of the tank sealings.

The coolant in this system has its own separate cooling circuit combined of two parallel connected radiators and a pump. The larger one of these two parallel connected radiators is positioned in the front of the center cooling pack, the second smaller one is located in front of the right-side wheel arch.

These cars are equipped with plastic intercooler pipes on both the hot and cold side. These pipes are a week link on any tuned car or in some cases even on a stock tune. The OE plastic pipes often crack / split leaving you with a boost leak.

We have designed upgrades for all these parts by advanced 3D scanning and 3D modeling in the scanned environment. We conducted CFD simulations on most parts and several tests to make sure we deliver the best performance upgrade!
