Just like people, cars have different pieces that help functionality and mobility. Although the air filter seems like something so simple, neglecting this important part of your car can be problematic down the road. Here’s what you need to know about the Hyundai Elantra Air Filter.

History of the Automobile Air Filter

Air filters weren’t always an essential part of the automobile engine. Although manufacturers and mechanics knew the engines were being damaged by pollutants and debris, they used other means to try and keep the engine clean. Eventually, they realized paper or fiber could get the job done. Back then, there was no such thing as air conditioners, so the cabin air filter wasn’t even a thought. The very first air filters were also round because automobiles had carburetors. Now they are flat and thin.

There are two air filters within the Hyundai Elantra – the engine filter and the cabin air filter. These filters help block environmental contaminants from entering the engine and ventilation system.

Where are the Air Filters Located on the Hyundai Elantra?

The engine air filter is located in the engine bay, and the cabin air filter is located in one of three places: under the dash, under the hood, or behind the glove compartment.

Specifications on the Hyundai Elantra Air Filter

Filters are based on model and year. In most models, the engine filter should be replaced every 15,000 to 30,000 miles. The cabin filter should be changed on a more consistent basis to ensure allergens are kept at a minimum within the vehicle.

Are There any Tell-Tale Signs of When the Air Filter Needs to be Replaced?

The engine will display the following signs:

  • A decrease in fuel efficiency
  • Decrease in acceleration
  • Dark smoke from the exhaust
  • Residue or grime buildup around the engine air intake
  • Dirty air filter
  • Weird noises when the car is stationary
  • Service engine light on the dashboard may come on
  • Slow engine startup

The cabin will have the following signs:

  • An abnormal increase in noise from the air vents
  • A decrease in airflow
  • Bad odors

Do These Air Filters Have to be Purchased from the Dealer?

No, they do not. Hyundai does make genuine OEM parts, but air filters can be purchased through an auto parts dealer or store.

Why Change My Air Filter?

A reduction in airflow can lead to unsafe conditions when driving, and also damage the climate control system.
