DO88 Side Charge Cooler Radiator BMW M3 M4 F80 F82

Side intercooler charge radiator for M3, M4 F8x - S55 engine

The S55 turbo engine uses a top-mounted water-cooled intercooler instead of a "normal" air-cooled intercooler.

The coolant in this system has its own separate cooling circuit made up of two radiators connected in parallel and a pump. The larger of these two parallel radiators is positioned at the front of the central cooling module; the second, smaller one is located at the front of the right-hand wing.

Reducing the water temperature in this circuit translates directly into better cooling of the turbocharged air (lower intake temperature). For this reason, it is important to have high-performance radiators in this system to keep the intake temperature as low and stable as possible during hard driving. Throughout all the tests we carried out while developing the entire BMW F8X M2C/M3/M4 product range, we clearly see how peak power is directly linked to the intake temperature (IAT - Intake Air Temperature).

Designed and manufactured in Sweden by DO88, fits in place of the original.

Team Lupos tip : "The importance of IAT (intake air temperature) is often overlooked, yet it can cause power losses, an increased risk of knock and engine overheating, which can damage components under intensive use. This radiator will help you protect your engine."
