Description
The B58 engine is renowned for its high power potential, but factory charge cooling components can become a bottleneck under demanding conditions. The do88 Charge Cooler Manifold addresses key weaknesses in cooling efficiency, airflow, and reliability, making it an essential upgrade for track and high-performance builds.
This direct-fit replacement features a Bar & Plate air-to-water intercooler core that improves heat dissipation and reduces intake air temperatures, ensuring consistent power delivery and maximum reliability under high boost.
Key Features & Benefits
- Bar & Plate Air-to-Water Intercooler Core – 102mm (4-inch) thick for superior heat transfer and 47% higher airflow vs. OEM.
- Lower Intake Air Temperatures (IATs) – Reduces intake temperatures from 41°C (OEM) to 26°C, preventing heat soak.
- Increased Power & Torque – Gains up to 18 HP midrange and 28 Nm torque, with peak 5 HP increase on a tuned BMW 340i.
- Supports Auxiliary Port Fuel Injection – Optional AN-8 fuel rail supports Injector Dynamics ID1050x-34-14 or Bosch EV14 Compact injectors. Includes blanking plugs if not in use.
- Nitrous & Methanol Injection Ready – 1/8” NPT ports on each intake runner for additional power modifications.
- Integrated Sensor & Vacuum Ports – Includes three 1/8” NPT ports for extra vacuum sources or boost monitoring.
- Enhanced Thermal Management – Aluminum construction withstands high boost pressures, with a thermal barrier spacer to reduce heat soak.
- OEM Engine Cover Compatibility – Designed to fit under the factory BMW and Toyota Supra engine covers for a stealthy install.
- No Modifications Required – Direct bolt-on installation with all necessary brackets and hardware included.
