Product Information

BMW Cylinder Head and Components diagram for 840i xDrive, M440i xDrive Gran Coupe, & more

An engine exhaust valve is a component inside the cylinder head that controls the release of burned gases from the combustion chamber after the air-fuel mixture has been ignited. It works in tandem with the intake valve, which allows fresh air and fuel into the cylinder. Exhaust valves are typically made of heat-resistant steel to withstand high temperatures and pressure.

• Poor Engine Performance / Power Loss: Incomplete exhaust evacuation reduces cylinder efficiency.
• Engine Misfires: Burned, bent, or leaking valves can cause misfires or rough idle.
• Excessive Smoke from Exhaust: White, blue, or black smoke may result from oil burning or improper combustion.

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.
