Product Information

BMW Air Intake Hoses and Parts diagram for X5

The engine air intake hose channels clean outside air through the air filter and into the intake manifold. Depending on whether your engine is naturally aspirated or turbocharged, these hoses are typically made from flexible plastic or rubber, which can degrade over time. Maintaining a clean and sealed air intake system is essential for proper combustion of the air/fuel mixture. A damaged or failing air intake hose can lead to reduced fuel efficiency, compromised engine performance, and improper fuel mixture, potentially causing damage to the engine.

• Check engine light: The check engine light may come on and stay on, indicating a lean condition
• Rough idle: The engine may run rough at idle and under load
• Intake noises: Additional intake noises may be heard during acceleration as air rushes in between cracks on a broken intake hose
• Poor fuel economy: If there is not enough air, the engine will demand more fuel to compensate, leading to poor fuel economy

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.
