The intake manifold takes incoming air from the intake and distributes it to each cylinder. Over the years the manifolds have gotten more sophisticated and complex. Most of the additional work that it does is emissions-related - recirculating vapors back into the engine to be re-used. But there are also performance innovations such as BMW's DISA variable intake runners. All of the modern innovations have a part behind it and here you will find replacement components.
In some BMW models there are performance improvements with intake manifolds. These intake manifold upgrades use mostly BMW parts and are a direct replacement for your stock manifold. We offer manifolds and kits to make the conversion work easier.
The DO88 Performance Charge Cooler represents a significant thermal management upgrade, engineered specifically for high-output applications where airflow volume and heat dissipation are critical. The system utilizes a premium 102 mm (4-inch) Bar & Plate core sourced from Garrett Motorsport, featuring a high-density fin architecture that maximizes heat transfer surface area while maintaining a low pressure drop. To ensure laminar flow and uniform air distribution across this core, the assembly employs CFD-optimized cast aluminum end tanks. This manufacturing approach allows for complex internal geometries that outperform traditional CNC-machined alternatives, prioritizing internal fluid dynamics and structural integrity under high-boost conditions over mere cosmetic appeal.
