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 crankcase oil vent system on the N52/N54 is one of its weakest and cheaply designed systems. We see crankcase vent issues on even stock engines but with more boost the problems are exponential. This Vargas upgraded PCV valve, and an oil catch can, are what the N54 engine needs and may alleviate most of your oil and boost leak issues. The PCV valve is supposed to let oil either return to the oil pan or pass through the intake manifold and get burned up in the combustion chamber. However, BMW used a weak plastic vent valve that doesn't seal well when under boost. Instead of closing and venting the oil out of the intake, it's forced through this valve and into the intake and coating your valves with oil residue and carbon. Most boost equals more oil forcing its way by. This upgraded N54 PCV valve uses higher grade materials, including aluminum, to provide a better seal and prevent oil from entering the intake. It's an easy install and a must-have item when considering any turbo work.

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 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.
