Description
Upgrade your BMW B58 engine with the do88 Performance Charge Cooler Manifold (MERA), engineered to improve cooling efficiency, airflow, and reliability. Designed as a direct replacement for the factory intake manifold, this advanced charge cooler addresses key weaknesses of the stock setup, making it an essential upgrade for performance enthusiasts.
Performance & Cooling Enhancements
The factory B58 charge air cooling system struggles with heat soak, especially in tuned applications or during track use. The do88 MERA manifold features an air-to-water intercooler core from Garrett Motorsport, providing superior heat dissipation. This results in lower intake air temperatures and reduced ECU intervention due to excessive heat.
- Core Thickness: 102 mm (4 inches), maximizing cooling efficiency.
- Cooling Rows: 11 water cooling rows vs. OE’s 6 rows.
- Lower IATs: Intake air temperatures reduced to 23°C compared to 40°C OEM.
- Airflow Increase: 42% higher airflow (874 CFM vs. 615 CFM at 1.45 psi pressure drop).
Power Gains & Performance Data
- Peak Power Gain: +5 HP (tested on BMW 340i 2017 with Bootmod3 Stage 2+).
- Midrange Power Gain: +18 HP.
- Torque Gain: +28 Nm.
- Designed in SolidWorks with CFD optimization for maximum performance.
High-Quality Construction & Design
- Cast Aluminum End Tanks: Precision-designed for even charge air and coolant distribution.
- Plug-and-Play Installation: No modifications required.
- Compatible with OE Engine Cover: Retains factory aesthetics while improving performance.
- Integrated Sensor Pad: Three 1/8” NPT ports for additional monitoring or vacuum sources.
- Thermal Barrier Spacer Included: Reduces heat transfer from the cylinder head, improving efficiency.
Auxiliary Fuel Injection & Additional Features
- Integrated Fuel Rail: Supports Injector Dynamics ID1050x-34-14 or Bosch EV14 Compact (K) injectors.
- Injector Blanking Plugs Included: Can be sealed when auxiliary injection isn’t used.
- 1/8” NPT Ports on Each Cylinder Runner: Supports nitrous or methanol injection.
- Oil Filter Accessibility: Allows quick oil changes without manifold removal.
Vehicle Fitment
The do88 Performance Charge Cooler Manifold is specifically designed for BMW models equipped with the B58 Gen 1 engine in the F-Series & G-Series platforms.
