Intake Manifold Upgrades & Components (DISA, Vacuum, CCV

BMW Intake Manifold Components (DISA, Vacuum, CCV, Etc) for BMW Z3 (1996-2002)

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.

When your CPV O-ring fails it causes a slow oil leak on the passenger side of the engine, making an oily mess that frequently resembles a rear main seal leak. Replacing the CPV with an upgraded o-ring ensures a long-term solution to this common problem.

The factory o-ring over time fails from heat cycling and oil exposure due to the Buna rubber used in OEM o-rings, while the included Viton Fluoroelastomer is resistant to a much higher temperature to ensure prolonged life without leaking.

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.

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
