BMW Intake Manifold Components (DISA, Vacuum, CCV, Etc) for BMW 5 Series E39 (1996-2003)

Clear BMW chassis

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 vent valve (CVV) holds and releases oil vapors that build up in the engine. It's the same type of system previously known as a PCV valve and the same deficiencies exist. Over time, the CVV will become saturated and clogged with oil. When this happens, the oil-rich vapors from the engine will back up into the intake tract and eventually into the combustion chamber. The oil added to the gasoline/air mix will cause misfires, carbon deposits, rough running, and blue smoke out the tailpipe. Replacing the CVV every 70,000 miles will ensure the correct and clean ventilation of oil vapor.

Replacement of the CVV can be done without removing the intake manifold. But replacing it during an M50 Manifold upgrade is the perfect time.

BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate. Replace all the components of the oil separator system together to prevent damage to all the aspects of your engine. As long as you have everything off, you can rest assured that new parts will last and be reliable. Don't forget to order a valve cover gasket to make your separator change easier.

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.

A bad DISA valve can cause a variety of issues, from a loud racket in the engine bay, hesitation at low rpm and a rough idle with lean codes. If the valve is making a loud noise, we recommend replacing it as soon as possible. It is possible for the pin holding the flap to be sucked into the motor causing serious damage. Very easy to replace, just need to undo the 4 bolts holding it to the intake manifold. Includes new mounting hardware
