The engine in your Audi vehicle runs on a mixture of oxygen and fuel. In order to run at optimal efficiency and deliver peak performance, it needs both delivered in the right ratio. Your induction system helps achieve that for the air intake side of the equation. Also known as cold air intake systems, they draw air in through the intake manifold and route it to the engine where it's distributed through the cylinders. The spark plugs then ignite the air-and-gas mix. It combusts, and the engine produces the power you need.
How Your Induction System Works
It all starts with air getting drawn in and passing through an air filter, which captures dust, debris, and other contaminants before they can sneak past into the engine and cause trouble. The vehicle air levels are regulated by three components. The first is a mass airflow sensor, which tracks air movement. The second is an air metering system, which delivers information to the engine's control unit (ECU). Lastly, oxygen sensors monitor the exhaust levels.
How to Detect Induction System Problems
Sadly, even the best induction system can begin to fail. If you notice any of the following signs, perform an inspection to determine the source of the trouble:
- The engine revs higher than normal when parked or in neutral
- The engine idles faster or slower than normal
- Your "Check Engine" dash light comes on
If that inspection shows that an induction system part needs replacing, do so as soon as possible. Our online auto parts catalog has everything you need for the project. Since we only sell the genuine Audi induction components that are guaranteed compatible with your vehicle, you can buy with confidence. Order now and save!
