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.

When it comes to S58 intake manifolds it doesn't get any better than this. The Burger Motorsports intake manifold replaces your factory plastic S58 manifold and intercooler with a direct-fit, high-flow, high-strength aluminum manifold. The intercooler core is double the size of the factory unit, and the manifold features port injection bungs located on the top of the manifold for easy access and optimal injector spray pattern. Includes high-quality o-rings and all required hardware. The BMS manifold has approximately 76.1% more internal volume than the OEM manifold
