BMW Intake Manifolds diagram for 750iL, 850Ci, 850CSi, 850i

An engine intake manifold is a component that distributes the air–fuel mixture to the engine’s cylinders. It’s mounted on the top or side of the engine and is typically made of aluminum, plastic, or composite materials.

• Engine misfires or rough idle – uneven air delivery to cylinders causes unstable combustion.
• Coolant or vacuum leaks – cracks or bad gaskets allow leaks that affect performance.
• Check Engine Light (CEL) – triggered by intake air imbalance, leaks, or sensor issues.

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
