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.
Idle control valves are a common problem for the E60 M5 and E63/64 M6. This kit was built to correct several engine performance issues caused by a failed idle controller, including: stalling, rough or low idle, no idle compensation for accessory loads, and a possible check engine light or failed emissions test.
