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 Black Market Parts Extended Intake Manifold Studs are the same great product that come with our N54/N55/S55 Port Injection Kit. These studs are compatible with any port injection kit and can even be used with stock manifolds. Each stud is designed like factory and is removed/installed with the same e-torx socket the factory 7mm studs are removed with so no switching tools or specialty stud installers needed.

The Precision Raceworks Phenolic Spacer is made in the USA from premium fiber impregnated phenolic material. With a Rockwell Hardness of 100 and a conductivity rating of 2.03 it is the perfect material for insulating between heat generating parts such as the cylinder head and other parts you wish to stay cool like the intake manifold. A phenolic spacer works by reducing heat transfer from the cylinder head to the manifold which results in reduction of intake air temperature, allowing for cooler air to enter the cylinders which is more dense and reduces chance of detonation in the cylinder. Our 1/2" phenolic spacer not only provides a thermal insulation between the cylinder head and intake plenum. It has also been designed to make use of factory O-Rings rather than messy gasket maker adhesive to ensure an air tight seal each and every time along with easy installation and removal.

The Black Market Parts OE-Spec Intake Manifold O-Rings kit is made with Viton capable of withstanding all fuels (including e85) as well as oils. These o-rings are made to OE specifications and are a direct replacement for the seals found in your factory intake manifold. These o-rings are also used in other BMP products such as our N54/N55 Port Injection Kit, S55 Port Injection kit, N54 Performance Intake Manifold, and N55 Performance Intake Manifold.
