BMW Intake Manifold Components (DISA, Vacuum, CCV, Etc) for BMW E39 M5 S62 5.0L

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.

Crankcase Vent Valve - Rein - BMW E39 M5 E52 Z8 is a crucial component for maintaining proper crankcase ventilation and preventing harmful oil buildup in the engine. Over time, the vent valve can become clogged with oil, leading to excessive crankcase pressure, poor engine performance, and increased carbon deposits. A failing valve can result in rough idling, misfires, and blue smoke from the exhaust. Replacing the crankcase vent valve at regular intervals ensures optimal engine efficiency and longevity.

Prevents oil-rich vapors from entering the intake system
Reduces the risk of carbon buildup and engine misfires
Direct-fit replacement for BMW E39 M5 and E52 Z8 models
Ensures proper crankcase ventilation for optimal performance
Helps eliminate excessive crankcase pressure and oil leaks
Manufactured to meet or exceed OEM quality standards

A damaged, leaking, or missing vacuum check valve can lead to a range of engine performance issues. As a critical component in the vehicle's vacuum system, the check valve ensures proper air flow and pressure regulation within various engine systems. If compromised, it can cause erratic idling, poor acceleration, or rough engine performance. Additionally, a malfunctioning vacuum check valve may trigger the check engine light and could cause your vehicle to fail an emissions test due to improper control of exhaust gases. Timely replacement of a faulty vacuum check valve is essential for maintaining engine efficiency, preventing further damage, and ensuring compliance with emissions regulations.
