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 end tank seals.
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 and split leaving you with a boost leak.
Do88 has designed upgrades for all these parts using advanced 3D scanning and 3D modeling. DO88 conducted CFD simulations and several tests to make sure they deliver the best performance upgrade!
