5 Signs You Need To Replace Your Car’s Air Filter

If you’re experiencing reduced fuel efficiency or noticing strange smells from your engine, it may be time to swap out the air filter. An old and clogged air filter will make your car sluggish, so you should pay attention to these signs you need to replace your car’s air filter. When you notice something is amiss with your vehicle, figure out the cause of the issue so you can fix it as soon as possible.

Reduced Fuel Efficiency

A clogged air filter makes the engine work harder to get the air it needs for combustion. This extra work can significantly decrease your car's fuel efficiency, leading to more frequent stops at the gas station. You’ll have to spend more on fuel that pollutes the air all because of a dirty air filter.

Strange Engine Noises

If you hear unusual sounds coming from your engine, such as hissing or coughing, it could be a sign that your air filter is dirty or clogged. These noises occur when your engine is struggling to take in air. Insufficient air in a combustion engine can lead to reduced performance and even damage, and ignoring these sounds can result in costly engine repairs.

Unpleasant Smells

An old or dirty air filter can cause unpleasant smells to emanate from your engine. These smells could be due to the accumulation of dirt, debris, and pollutants that are stuck on the filter. If you notice strange odors, it's time to check your air filter. A new air filter will eliminate these odors and improve your car's air quality.

Decreased Horsepower

A clogged air filter can negatively impact your car's horsepower. A clean and functioning air filter allows for optimal airflow into the engine, which is essential for combustion. If you have noticed a decrease in acceleration or power, it could be a sign that your air filter is dirty and needs a replacement.

Difficulty Starting Your Car

If you're having trouble starting your car or it takes longer than usual, the air filter could be dirty. A clogged filter can prevent air from entering the engine during ignition, making it difficult for your car to start. Ignoring this issue can lead to further complications and may even leave you stranded on the side of the road!
