Description
DO88 BMW F8X S55 Performance Chargecooler is a performance upgrade developed by DO88 for the applications listed below.

Key Features
- 85% larger core volume than OE
- 298 CFM versus 256 CFM at 0.025 bar in DO88 testing
- 39°C versus 48°C post-cooler temperature in the stated comparison
- Up to 25 hp mid-range and 52 Nm gain in DO88's stated Stage 1 testing
- TIG-welded aluminium construction
- Replaces BMW OE reference 17517846235
Vehicle Compatibility
BMW M2 Competition F87 2019-2020; BMW M3 / M3 Competition F80 2015-2018; BMW M4 / M4 Competition / M4 GTS / M4 CS F82/F83 2015-2020.
Fitment note: Vehicle specification can vary by market, model year and factory equipment. Check the listed chassis, engine and transmission requirements before ordering.
DO88 develops model-specific cooling and airflow components using vehicle measurement, CAD/3D modelling and physical testing. This product is intended for owners looking to improve durability, thermal control or airflow on fast-road, tuned and track-focused BMW applications.
Chargecooler alone or a BigPack?
ICM-320 is the top-mounted S55 chargecooler. For a package with additional pipes or charge-cooling radiators, compare the do88 S55 BigPack configurations. Those components are separate from this chargecooler listing.
The radiator-containing BigPack configurations have an M2 Competition exclusion, so select the package by component and chassis. The original N55 M2 requires its own cooling application. The power and temperature figures above describe do88's stated test conditions; results depend on the car, tune and operating conditions.
Compare the do88 cooling and hose range by vehicle and cooling circuit. Match the application and part number for each component.
