OEM Mazda Induction Parts

Refine Results

Your Mazda vehicle's induction system, also called an air intake, pulls air through your intake manifold and into your engine, distributing it throughout the engine's cylinders. When the air mixes with your fuel in the right ratio, your spark plugs ignite them both, and they combust. This is how your engine generates the power it runs on.

How induction systems work is straightforward. First, air from outside gets drawn through an engine air filter, which captures dirt, dust, pollen, and other contaminants. Second, air levels are regulated by a mass airflow sensor (which tracks air movement), an air metering system (which feeds air info back to your engine's control unit/ECU), and one or more oxygen sensors (which track exhaust levels). Some engines have cold air intakes, which, dependent on where they're located, can suck in cooler and denser air, enhancing power output slightly.

When induction system parts stop working the way they should, though, you'll notice it. Signs of a bad or failing air intake include:

  • Your engine revving faster than normal either in neutral or when parked
  • Idling faster or more slowly than normal
  • A lit Check Engine light on the dashboard

Your Check Engine light generally means engine performance issues, but revving and idling problems often mean induction system failure. The best way to determine the cause of these problems is to do an inspection.

Repair Your Induction System with Genuine Mazda Parts

If you determine air intake repair to be necessary, you're in luck. Our online store has the induction parts you need for the project, straight from your OEM. You can buy them right here, too. Order today and we'll deliver them right to your door.
