BMW Grille diagram for Z4

A vehicle's grille is usually an openwork structure on the front of the vehicle, positioned in front of the engine bay. It serves both functional and aesthetic purposes, as it is designed to allow airflow into the engine compartment to help with cooling while also enhancing the vehicle's appearance. The grille is typically located between the headlights, often below the front bumper in many modern cars, and may be made of metal, plastic, or a combination of materials.

• Engine Cooling: The primary function of a grille is to allow fresh air to flow into the engine bay, which helps regulate engine temperature and cools the radiator. Without this airflow, the engine could overheat, which can lead to engine damage
• Aerodynamics: Some vehicle grilles are designed to improve the car's aerodynamics by directing airflow around the vehicle in a way that reduces drag

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.
