Audi VW Engine Intake Valve - Genuine Audi VW 04L109601D

Product Information

An engine intake valve is a key component of an internal combustion engine. It is located in the cylinder head and controls the entry of the air-fuel mixture into the combustion chamber. The valve opens at a precise moment in the engine cycle, allowing the correct amount of air (or air-fuel mixture) to enter the combustion chamber. It then closes tightly to seal the chamber so combustion can occur efficiently.

• Engine Misfires: A faulty valve may not seal properly, causing incomplete combustion. You may notice jerking, rough idle, or hesitation when accelerating.
• Loss of Power & Poor Acceleration: If the air-fuel mixture cannot enter efficiently, the engine produces less power. The car may feel sluggish or struggle on inclines.
• Backfiring or Popping Sounds: Improper sealing can cause fuel-air mixture to ignite in the intake manifold. This creates popping sounds during acceleration or deceleration.

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.
