DO88 Charge Cooler Manifold, BMW F-Series (B58)
$1,999.66
The B58 engine, introduced with the F-series, has proven to be a real gem of an engine, capable of high outputs with great character. However, there are a few week points that needs addressing, both for performance and reliability. The B58 comes equipped with a water-to-air charge cooler that is coupled a with front-positioned heat exchanger (water radiator). The heat exchanger serves to cool the water circulating through the charge air cooler, which in turn helps dissipate heat from the charge air before it enters the engine. The charge air cooler is integrated into the intake manifold on the B58, making it an intricate and dense construction, demanding accuracy in the design and execution by us as an aftermarket producer.
Challenges with the factory components
Owners of tuned B58 engines often confront the issue of rapid heat soak in the charge air cooling system, particularly when the vehicle is used for track days. Elevated intake air temperatures may prompt the ECU to decrease the power output, or even switch the car into limp-home mode. Regular spirited street driving can also cause similar issues.
Additionally, the factory installed direct injection system, with its obvious benefits, is not well suited for high horsepower applications or ethanol flex fuel usage. To be able to inject more fuel, many turn to installing port fuel injector spacers between the intake manifold and the cylinder head. The downside with this solution is that it positions the injectors in a funny angle. As a result, the fuel hits the walls of the intake runners, leading to potential fuel puddling.
As is often the case, factory components can become limiting factors when you strive for high power levels, particularly in terms of airflow. The factory (OE) intake manifold is such a component, that not only restricts airflow but also poses a significant risk of cracking under high boost levels, due to its plastic construction.

FEATURES:
- Utilizes a high performance, Bar&Plate, air-to-water intercooler core, 102 mm (4”) thick. 11 water cooling rows, OE 6 rows.
- Lower inlet air temperature under identical conditions: 26°C compared to OEM 40°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: 873 CFM (615 CFM), 42% 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).
- Optional fuel rail (not included) 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).
- 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 engine cover. It even fits with modification when running with the auxiliary port injection fuel rail (Only confirmed on BMW 340i F30/F31).
- 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).
