Description
Maximize the cooling efficiency and airflow of your BMW B58 Gen 1 engine with the do88 Performance Charge Cooler Manifold. Engineered for performance, reliability, and adaptability, this high-flow aluminum manifold is designed to handle high boost levels while reducing intake air temperatures, ensuring consistent power delivery during street, track, and drag racing applications.
Factory Limitations & Performance Challenges
- The OEM water-to-air charge cooler is prone to heat soak, leading to performance loss, especially in tuned B58 engines.
- The plastic factory intake manifold restricts airflow and is vulnerable to cracking under high boost.
- The direct injection-only setup can be limiting for high-horsepower applications, requiring additional fuel delivery solutions.
The do88 Solution – Advanced Cooling & Performance
- High-performance Bar & Plate air-to-water intercooler core with a 102mm (4-inch) thick design and 11 cooling rows (OE has only 6).
- Optimized cast aluminum end tanks, developed using Computational Fluid Dynamics (CFD) for maximum airflow and even charge air distribution.
- Thermal barrier spacer included, insulating the aluminum manifold from the cylinder head's heat, reducing intake air temperatures (IATs) and improving efficiency.
- Integrated sensor pad with three 1/8” NPT ports for additional measurements or as vacuum sources (sealed with included plugs).
- Individual 1/8” NPT ports on each cylinder runner, allowing for nitrous or methanol injection (sealed with included plugs).
- Designed for direct fitment, requiring no modifications for installation.
Performance Gains
- 42% increased airflow over OEM, measured at 873 CFM vs. 615 CFM at 1.45 psi pressure drop.
- Lower intake air temperatures (IATs): 26°C vs. 40°C with OEM under identical conditions.
- Peak power gain: 5 HP on a bootmod3 Stage 2+ tuned BMW 340i (2017).
- Mid-range power gain: Up to 18 HP.
- Torque increase: Up to 28 Nm.
Fueling & Compatibility Features
- Pre-configured for auxiliary port fuel injection, with an optional AN-8 fuel rail for Injector Dynamics ID1050x-34-14 or Bosch EV14 Compact (K) fuel injectors.
- Injector blanking plugs included for those not using port injection.
- Retains compatibility with the OEM engine cover. With modifications, it can also accommodate the auxiliary fuel rail (confirmed on BMW 340i F30/F31).
Easy Maintenance & Installation
- Quick-access spin-off oil filter design, eliminating the need to remove the manifold for oil changes.
- All essential brackets included for proper fitment of wire harnesses and the engine cover.
