The Importance of Regular Filter Replacement

Date: Dec 28, 2023

Routine vehicle maintenance is a must for smooth performance on the roads of Lawrence and Trenton. This includes regularly replacing the filters in your vehicle like the fuel filter, cabin air filter, and engine air filter. In the guide below, we answer common questions like:

  • What does an engine air filter do?
  • What is a cabin air filter in a car? 
  • Why is car fuel filter replacement so important? 

When should you replace the filters in your vehicle? For most drivers in the Hamilton area, this service should happen every 12,000 miles or 12 months. Because the answer to this question can vary based on your particular make and model, we always recommend taking a look at your owner’s manual. 

What Does an Engine Air Filter Do? 

What does an engine air filter do? Your vehicle is outfitted with an engine air filter to prevent harmful contaminants from making their way into the engine. Thanks to the engine air filter, your engine’s air supply is free of debris. When the engine air filter is clogged, vehicle performance is compromised. 

If your engine air filter is not replaced at the recommended interval, you will likely notice reduced engine power, decreased throttle response, weakened acceleration, and increased engine wear. 

Be on the lookout for these warning signs of a bad engine air filter: 

  • Problems accelerating
  • Difficulty idling
  • Engine that sounds like it has a problem taking in air 
  • Black smoke coming from the exhaust system
  • Check Engine light is illuminated on your dashboard 

Why is Car Fuel Filter Replacement So Important? 

Fuel accumulates contaminants on its journey to your local gas station. This debris can get into the fuel tank and clog the fuel injectors. A clogged fuel filter can lead to a drop in fuel pressure, which has a negative impact on vehicle performance. 

Watch for these issues: 

  • It’s more difficult to start your vehicle, or it doesn’t start at all
  • Lower fuel economy
  • The engine misfires
  • The engine stalls
  • Engine performance is sluggish 

What is a Cabin Filter in a Car?

What is a cabin filter in a car? Your vehicle has a cabin air filter to keep dust, pollen, dirt, and other pollutants out of your vehicle’s interior. If you have allergies or a sensitive respiratory system, it’s even more important to replace the cabin air filter regularly. 

If your cabin air filter is due for replacement, you may experience the following:

  • Strange odor coming from the vents
  • Decreased airflow from the vents
  • Worsened cabin air quality 
  • Strange sounds when using the vents
  • The heat or A/C system is not operating properly
