How Does an Air Induction System Work?

Induction systems, also called air intakes, draw the oxygen engines need into an intake manifold to be spread throughout their cylinders. First, air enters an engine through an engine air filter, which removes airborne contaminants in the process. (Alternatively, induction can be located near a fender or above a wheel well, making it a cold air intake. Doing this enables pulling in cooler and denser air, which can slightly improve engine power.) Then, air levels are regulated.

How Do Induction Systems Know How Much Air to Use?

Using three components:

• A mass airflow sensor to measure air movement
• An air metering system to give feedback to an engine control unit (ECU, for short)
• An oxygen sensor (or several sensors) to monitors exhaust levels

When everything works together properly, an engine runs as well as it can. When things don't, though, you'll start to see the signs:

• A lit Check Engine light, which means engine performance problems
• Your engine revving too fast in neutral or when parked
• Faster- or slower-than-normal idling

The last two usually suggest induction system failure. Luckily, if you run an inspection and it indicates induction repair is required, our auto parts store has the best parts for your project: genuine Mopar. You can even order them online. Buy now!
