2006-2008 BMW Z4 Intake Manifold Plenum. This manifold is only a direct replacement for 2006-2008 3.0si models with the N52 B30 engine. Removed from a 2008 Z4 3.0si equipped with the 6 speed manual transmission. Since this is off of a manual transmission vehicle, there are some parts which are different than the automatic version, which you would need to transfer over from your vehicle if you have an automatic transmission. It is a common upgrade for other N52 motor cars such as the 2006-2008 3.0i BMW Z4. It is not a direct bolt on upgrade though, as it will need modifications and an ECU tune to function properly. Please fully research this upgrade before purchasing this part for any car besides the model it originally came off of. The manifold is in good working condition off of a running and driving car, fully tested prior to removal from the vehicle. There are no cracks or breaks in the manifold. Includes everything as pictured, which includes the DISA valves. Both DISA valve motors are in good working condition with no loose play in the butterfly valve. The oil seals on both valves were in good physical condition with no rips or tears. You will need to reuse some of your existing hardware for installation.
