Yet, when the air quality of our engine decreases and loses its efficiency, it is a significant decrease in performance, handling, and fuel economy.

Additionally, when the air inside your engine is dirty, the life expectancy of your engine can be reduced dramatically.

So. how can we maintain the air quality of our engine? The answer is getting a proper air filter.

Basics of Air Filters

Your engine is constantly exposed to dirt, moisture, and all other contaminants of the atmosphere.

So, the sole job of your air filter is to keep the air clean all the time.

Even a small amount of accumulated contaminants can significantly reduce the performance of your engine, or worse, causing a complete failure.

Your typical air filters are located in an air box, between the fresh air inlet and your engine.

So, to replace your air filter, you will first need to remove the clamps or screws of your airbox, which is fairly easy.

The hard part, however, is choosing the right air filter that can do the job right.

There are proper air filters that work just as intended, and some that simply don’t.

Here, we have researched the best engine filters available in the market today, and we will review some options you can consider.

There are two key factors we considered when choosing the best engine air filter: airflow and filtration quality.

Air Flow

A free-flowing air filter is extremely important to maintain an adequate amount of air supply to your engine. As the filter accumulates dirt, it will flow less air.

Filtration Quality

Since the main job of a vehicle air filter is to catch contaminants, filtration quality is the most important factor.

MicroGard air filters are known to be the best in both filtration and airflow. However, there are several issues:

  1. MicroGard air filters are vehicle-specific. So, you will have to be really careful about checking the compatibility. Then, there can be several different options for your vehicle. So, choosing the best one for your vehicle can be really difficult.
  2. Even after all that, MicroGard air filters are only available in selected authorized dealers. So, you don’t have much versatility.

With those issues being said, we have tested some of the best alternatives available on the market.

The criteria remain the same: the air filters we recommend should have filtration and airflow levels on par with the best MicroGard air filters.
