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.
