Product Details

The DO88 Performance Charge Cooler represents a significant thermal management upgrade, engineered specifically for high-output applications where airflow volume and heat dissipation are critical. The system utilizes a premium 102 mm (4-inch) Bar & Plate core sourced from Garrett Motorsport, featuring a high-density fin architecture that maximizes heat transfer surface area while maintaining a low pressure drop. To ensure laminar flow and uniform air distribution across this core, the assembly employs CFD-optimized cast aluminum end tanks. This manufacturing approach allows for complex internal geometries that outperform traditional CNC-machined alternatives, prioritizing internal fluid dynamics and structural integrity under high-boost conditions over mere cosmetic appeal.

Designed for the technical enthusiast, the manifold integrates advanced features such as a thermal barrier spacer equipped with custom FKM-silicone O-rings to decouple the assembly from cylinder head heat soak. The hardware is fully modular, featuring a pre-configured outlet tank for auxiliary port fuel injection, compatible with ID1050x-34-14 or Bosch EV14 Compact injectors, alongside dedicated 1/8” NPT ports for nitrous or methanol injection. Furthermore, the inclusion of integrated 3-port pads for vacuum or sensor data, along with dual 1/8” BSPT ports for coolant temperature monitoring and system bleeding, provides comprehensive diagnostic capabilities. Despite these professional-grade features, the unit is precisely clearanced to fit beneath the OEM engine cover, maintaining a factory aesthetic without compromising on its vast performance capabilities.

Product Details:

Replaces BMW # 11618647977
Utilizes a high performance, motorsport grade, Bar&Plate, air-to-water intercooler core from Garrett, 102 mm (4”) thick. 11 water cooling rows, OE 6 rows.
Lower inlet air temperature under identical conditions: 23°C compared to OEM 41°C. Exact figures to be found in the diagrams under the product pictures.
More air to your engine, less backpressure and better airflow! Airflow at 0,1 bar / 1,45 psi pressure drop: 874 CFM (595 CFM), 47% higher! See diagram under the product pictures.
Peak powergain of 5 hp! Measured on car with bootmod3 Stage 2+ (BMW 340i 2017).
Highest midrange powergain of 18 hp!
Highest torque gain of 28 Nm!
Designed in SolidWorks using Computational Fluid Dynamics (CFD).
Easy access to spin-off oil filter for quick oil changes – no need to remove the manifold every oil change.
Integrated sensor pad with three 1/8' NPT ports to measure additional parameters (sealing plugs are included).
Included fuel rail (included in the MERA version) for auxiliary top feed port injection.
Injection plugs for each cylinder runner is included.
Individual 1/8' NPT ports on the top of each cylinder runner for nitrous or meth injection (sealing plugs are included).
Individual 1/8' BSPT breather ports for both inlet/outlet water connections on the back of the manifold for an easy air-bleeding of the system (sealing plugs are included).
Plug-and-play design, requiring no modifications to install.
Included are all the essential brackets needed for various components, such as wire harnesses and the engine cover.
Can be installed with OE or aftermarket engine covers (with OE connections). It even fits with small modification when running with the auxiliary port injection fuel rail.
Thermal barrier spacer included, engineered to insulate the aluminum intake manifold from conductive heat transfer from the cylinder head.
Custom made high spec FKM-silicone O-rings included for both the thermal barrier spacer and intake manifold (12 pcs in total).

* For vehicles equipped with a Mild Hybrid engine, the alternator requires modification. Refer to Step 11 in the installation instructions for details.

Not for sale or use in the state of California on any pollution-controlled vehicle as per the California Air Resources Board.
