If you don't change your cabin air filter, it can become clogged over time and restrict the airflow into the car. This will lead to reduced fuel efficiency, increased emissions, and possible problems with the engine. In worst case scenarios, this could result in a failed engine or even an accident.
Unless the air filter is completely clogged or blown into pieces like one of mine was, it won't really change anything. If the old one was bad then it can definitely give you more airflow which would make your car more efficient, giving you slightly higher MPG and horsepower, but probably not enough power to notice.
Damaged Spark Plugs: Driving with a clogged air filter for too long can cause an excess of unburnt fuel, leading to carbon deposits on your spark plugs. This, in turn, can cause misfires, rough idling, and difficulties starting the engine.
Regularly checking and replacing your car's air filter helps maintain good air quality by preventing dirt and dust particles from entering the engine. Not only will this help ensure that your engine is getting sufficient airflow, but it can also help improve fuel efficiency and reduce environmental impact.
Most engine air filters will cost between $20 to $85, depending on the year, make, and model of your vehicle, and whether you do it yourself or take your vehicle to the dealer or a mechanic.
Just like how a low fan speed on a hot day will never make you feel cold enough, a clogged cabin air filter restricts airflow, which can make your AC seem less effective. So, while a new cabin air filter might not make your AC 'colder,' it certainly contributes to a cooler and more comfortable cabin experience.
Cleaning the air filter only improves its appearance. When should an air filter be replaced? The air filter should be replaced after the period indicated by the vehicle manufacturer.
Your engine does not work well with contaminated air. The engine does not put out enough power or performance when it is dirty. If your car jerks when you try to accelerate, it may not be getting enough oxygen. The horsepower in your vehicle is dependent entirely on the amount of oxygen the engine receives.
Air filters that are overdue for a change are a common cause of HVAC system failure. Over time, dirt builds up in the heating and AC filters, causing components such as the motor to go into overdrive, which may eventually overheat your unit.
A bad air filter will sound like there is wind blowing in your car. Since the filter does not properly fit the bearing, the wind will start to blow from the edges of the filter. This air leakage from the edges of the filter will lead to a whistle-like sound or a wind-blowing sound in the vehicle.
Generally speaking, you should replace your car air filters every 12 months or 12,000 miles, whichever comes first. If you have a cheaper, thinner engine air filter, you may need a new air filter more frequently.
For some cars, it's a simple as releasing a few spring clips on the edge to access the filter. On others, a few screws hold the housing closed, and the air duct may need to be loosened or removed first. Identify any fasteners that need to be removed, then use your screwdrivers, pliers, or socket set to do it.
Neglecting your air filter can lead to several issues. Over time, it can cause reduced fuel efficiency, diminished horsepower, and even engine damage. Keeping up with this small maintenance task can save you from more significant, expensive problems.
A filter that is clogged with dirt is an obvious sign of a dirty air filter. Performing a visual inspection is an easy way to know if your air filter needs to be changed. A brand new air filter is white or off-white in color, while a dirty air filter will appear darker with the dirt and debris visible.
Most cars are designed to last between 150,000 to 200,000 miles.
A dirty air filter can cause your vehicle to throw a Check Engine code. During this instance, the Check Engine Light of your vehicle will turn on. The light turns on because your vehicle is sensing that its engine isn't receiving enough air.
If you breathe in air that has not been filtered or is filtered through a dirty cabin air filter, you may notice that you get sick more often, have difficulty taking deep breaths, and have allergies that are exacerbated. Your car's health may be at risk, too.
