Unlock Maximum Airflow and Cooling with the do88 Inlet Manifold & Intercooler – BMW G8X M2, M3, M4 (S58)

Unleash the full potential of your S58-powered G8X M-car with the do88 Inlet Manifold and Intercooler – a high-performance, track-proven solution designed to address the limitations of the factory plastic manifold. This motorsport-grade upgrade improves airflow, reduces intake temperatures, and offers built-in support for future fuelling upgrades like meth injection or port injectors.

Why Upgrade?

Factory Limitations on Tuned S58 Engines

The OEM S58 inlet manifold combines a plastic intake plenum with a built-in water-to-air intercooler core. While effective in standard applications, it presents several key weaknesses:

• Heat soak under repeated or extended track use

• Risk of end-tank failure at raised boost pressures

• Airflow restrictions at high power levels

• No provision for additional injectors or meth injection

do88’s solution overcomes each of these with advanced materials, engineering, and real-world development.

Key Features

Motorsport Cooling & Airflow

• Huge 127mm (5”) Bar&Plate core – 62% larger than OEM

• Densely packed fins for maximum heat transfer

• Improved airflow: 511 CFM @ 0.05 bar vs. 422 CFM OEM (21% gain)

• 28.5°C intake temps vs. 33°C OEM during testing

• CFD-designed cast aluminium end tanks for even air/water distribution

Integrated Fueling and Meth Support

• AN8 fuel rail included – compatible with ID1050x-34-14 or Bosch EV14 short injectors

• Built-in injector ports and plugs for optional port injection

• 1/8” NPT ports on each runner for methanol or nitrous oxide

• Three additional 1/8” NPT sensor/vacuum ports included on the outlet

Advanced Heat Isolation

• Thick thermal spacer reduces heat transfer from the cylinder head

• Spacer uses precision-milled grooves and custom FKM O-rings (12 total)

• Eliminates need for unreliable sealants used in competitor kits

Real-World Practicality

• Full oil filter access retained

• All required fittings, brackets and hoses included

• Plug-and-play fitment – no fabrication required

• Engineered in Sweden and extensively CFD tested

Compatibility

• BMW G80 M3

• BMW G82 / G83 M4

• BMW G87 M2
  For all S58 engine variants, including Competition models.

Supporting Upgrades Recommended

• do88 Performance Front Water Cooler (Heat Exchanger)

• High-flow charge pipes and downpipes

• ECU calibration / custom tuning

• Upgraded fuel system for flex-fuel applications
