OEM INFINITI Air Intake Components Online

Refine Results

An air intake, also called an air induction system, draws oxygen into an engine through an intake manifold, where it's distributed among cylinders. When it mixes with gas in the right ratio, spark plugs combust the mix. It burns, producing the power that runs an INFINITI vehicle.

How air intakes work is simple. Air goes through an engine air filter, where its airborne contaminants are removed, and then it gets regulated by a mass airflow sensor, an air metering system, and oxygen sensors. The first measures air movement. The second feeds back to an engine control unit (ECU). The third monitors exhaust levels. If an engine uses a cold air intake, it can pull in chillier and therefore denser air, slightly improving power output.

When air intake parts don't work properly, though, they can cause trouble. Aside from a lit Check Engine light, signs of it include an engine that revs too fast (both in neutral and when parked) and idling faster or more slowly than normal. The first symptom suggests general engine performance problems. However, the last two indicate possible air intake system failure.
