When Should You Change Your Air Filter?


The air filter is tiny but tremendously important. It is responsible for cleaning the air that reaches your engine by capturing sand and dirt and preventing them from entering your engine. 

Auto experts suggest that you should consider replacing your air filter after 15,000 to 30,000 miles since the last filter change. However, this number range is slightly flexible as a lot depends on the type of engine and the kind of roads you usually drive on. 

If you drive a turbocharged engine, you would need to replace your air filter more frequently. Similarly, if you drive a lot and that too on rough, unpaved roads, then again, you will need to change the filter more often.

Even if you drive quite less and usually on tame, city streets, you must still change your filter after a maximum of 3 years since, with time, they get fragile and inefficient. Seated in its air filter box, the air filter gets clogged up with dirt, causing breathability issues for your engine downstream. 

More clogging means less air is reaching your engine. This, in turn, leads to your engine consuming more fuel for power resulting in lowered performance. Below are some warning signs your vehicle gives when it needs an air filter change in Freehold, Asbury Park, and Belmar:

Lowered Gas Mileage

A blocked air filter means less oxygen for your engine. The engine compensates for this lack of oxygen by burning more fuel, thereby decreasing fuel efficiency.

Engine Trouble

Another symptom of a closed-up filter is if your engine suddenly refuses to start quickly. Lack of air can negatively impact the spark plugs causing your engine to miss. The spark plugs can be damaged severely and make your car cough when idling. Such misfiring and distressing sounds might be an indication of a blocked air filter.

Lowered Horsepower

Another symptom of a clogged air filter is when your car has trouble accelerating. If it takes longer for your vehicle to respond, it might be time to check the air filter.

Dirty Air Filter

A mechanic usually inspects the filter during an oil change; however, you can also easily take the filter out and observe its condition for yourself. If it's dark, and light does not go through it, it might be due for a replacement.
