Product Details

The do88 MERA Charge Air Cooler Intake Manifold replaces the factory plastic intake manifold to maximize charge air cooling and airflow on BMW B58 and Toyota Supra A90 engines. Factory B58 manifolds suffer from rapid heat soak and physical cracking under high boost pressures. The do88 aluminum manifold utilizes a Garrett Motorsport bar-and-plate core and cast end tanks to drop intake air temperatures from 41°C to 23°C while increasing airflow by 47 percent..

Technical Specifications

Replaces BMW # 11618647977
Core Construction: 102mm (4-inch) thick Garrett Motorsport bar-and-plate air-to-water intercooler core.
Cooling Density: 11 water cooling rows compared to the factory 6 rows.
Thermodynamic Efficiency: Decreases intake air temperatures to 23°C from the 41°C factory baseline under identical operating conditions.
Airflow Capacity: Flows 874 CFM at a 0.1 bar (1.45 psi) pressure drop, yielding a 47 percent volume increase over the factory 595 CFM manifold.
Performance Metrics: Delivers peak power gains of 5 horsepower, midrange gains of 18 horsepower, and peak torque gains of 28 Nm

Features and Benefits

Cast Aluminum Construction: Replaces the factory plastic manifold to eliminate structural cracking failures under high boost pressures.
Thermal Isolation: Utilizes a specialized thermal barrier spacer equipped with 12 custom FKM-silicone O-rings to prevent conductive heat transfer from the cylinder head to the aluminum manifold body.
Auxiliary Fueling Integration: Pre-configured with a custom AN-8 female threaded fuel rail for port injection with Injector Dynamics ID1050x-34-14 or Bosch EV14XK (short) fuel injectors. This corrects the improper spray angles and fuel puddling caused by traditional injector spacer plates.
Direct Port Injection Support: Cast with individual 1/8-inch NPT ports on top of each cylinder runner to accommodate direct port injection of methanol or nitrous.
Auxiliary Measurement Access: Incorporates an integrated 3-port pad on the inlet tank casting featuring three 1/8-inch NPT ports for additional sensor parameters or vacuum sources.
Efficient Coolant Purging: Integrates two 1/8-inch BSPT ports on the rear water tank to facilitate complete air bleeding from the water circuit and enable precise coolant temperature monitoring.
Factory Serviceability: Engineered to maintain unobstructed clearance for the factory spin-off oil filter, allowing routine fluid services without manifold removal.
Engine Bay Integration: Designed to fit underneath the factory engine cover using included brackets to retain OEM aesthetics, accommodating the auxiliary fuel rail with minor cover modification.
Crankcase Sealing: Includes designated hardware to permanently cap the crankcase vacuum connection and fuel tank breather line for high-horsepower engine configurations.

* 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.
