DO88  Performance Chargecooler / Intercooler + Pipes

To Fit: 

  • BMW M2 Competition - 2019-2020 - Model: F87
  • BMW M3 / M3 Competition - 2015-2018 - Model: F80
  • BMW M4 / M4 Competition / M4 GTS / M4 CS - 2015-2020 - Model: F82 F83

This product offers you the various BigPack configurations that are available for the BMW M2 / 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 a “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 the engine or leaking boost pressure out of the tank seals.

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 centre 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 weak 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 modelling in the scanned environment. We conducted CFD simulations on the majority of items as well as many tests to make sure we deliver the best available performance upgrade!

You can choose between three different options for this product.

  1. Intercooler and both intercooler pipe kits
  2. Intercooler and both radiators for intercooler system (COMING SOON)
  3. Intercooler, both intercooler pipes and both radiators for intercooler system (COMING SOON)

Our performance intercooler helps your engine to make more power both by lowering the intake air temperature and lowering the pressure drop! It is a bar and plate unit with 3D freeform designed end tanks TIG welded to the core. It has a core volume 85% larger than the stock intercooler and outperforms the stock unit both when it comes to air flow and with cooling efficiency. 16% better flow and 9°C lower IAT, so with both better flow and lower IAT this is a true upgrade!

Our radiators for the charge air cooling circuit lowers the water temperature in the charge air cooling system circuit. This is equal to lower intake air temperature which gives both more power and a more persistent performance. We achieve this by increased cooling face area, increased core thickness and well composed cores made with multichannel tubes!

Our intercooler piping, both the one that goes from the turbochargers to the intercooler and the one that goes from intercooler to throttle body is designed to add durability and at the same time improve air flow. It is not easy to improve both reliability and improve air flow as the stock pipes flows well. With our software flow simulation and physical flow verification abilities we are sure that we are making improvements which is more than most suppliers of this kind of pipes can say!
