Audi VW Engine Intake Manifold Bolt - Genuine VW Audi N91063801

Product Information

An engine intake manifold bolt is a high-strength fastener that secures the intake manifold to the engine cylinder head. These bolts ensure a tight seal between the manifold and the gaskets, preventing air, coolant, or vacuum leaks that could disrupt engine performance. Properly torqued manifold bolts are essential for maintaining engine efficiency, smooth airflow, and reliable combustion.

• Vacuum or coolant leaks around the intake manifold area.
• Rough idling or engine misfires, caused by unmetered air entering the system.
• Loose or missing bolts, leading to poor sealing and potential gasket failure.

About Genuine VW Audi

The Volkswagen Group, also known as “VAG”, consists of Volkswagen, Audi, Lamborghini, Bentley, Bugatti, Porsche, Ducati, MAN, Scania, SEAT, and Skoda. The original parts used by VAG to build your car are available as replacement parts under the “Genuine VAG” brand. Manufactured under the direction of VAG, expect excellent quality and a premium price since these parts are available exclusively through the VAG Dealership network.

You may not realize this, but the parts that make up your VAG are not necessarily manufactured by VAG. No cause for concern, as VAG designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for VAG 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 VAG parts box and find an OEM branded part inside, simply with the addition of a VAG 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.
