Air filters

The basic job of an air filter in cars is to send purified air to the combustion chamber where the air mixes with the fuel and the combustion process takes place. More oxygen means better combustion; therefore, better performance, fuel efficiency, and cleaner emissions. Keeping in mind the costs, car manufacturers make balanced type of air filters which allow clean air (oxygen) to go inside but with some restrictions. A cotton air filter’s life cycle is somewhere between 10,000 to 20,000 kilometers depending on manufacturer’s recommendation. Here steps in the concept of cotton or free flow air filter, as it is commonly called. A cotton air filter is made up with special quality materials that are very strong in strength which allow completely pure airflow to the combustion chamber for better air/fuel mixture, which helps the engine to perform with increased efficiency. There are three types of cotton air filters.

Now below are their pros and cons:
Pros of car air filters (cotton):

• More purified and free flow air, so better combustion.
• Increased engine life and strength to perform optimally.
• Increased fuel efficiency (though negligible)
• Increased performance (again hardly noticeable) but clearly visible and measurable in cold air intake kits’ case.
• Cleaner emissions due to better fuel burning.
• More free revving engine and improved deeper exhaust note.

Cons of car air filters (cotton):

• Expensive to buy.
• Special kit for cleaning and lubricating.
• Have to do the cleaning and lubricating process yourself.
• More frequent cleaning due to greater dust blocking (though it is a good thing showing that filter is doing its job better).

But now the biggest pro which goes in favor of these filters is their life. Approximately 1600000 kilometers means no need to change the filter for the whole life of your car. In fact if you buy a universal car air filter, it will continue in your second, third, and even fourth car (if maintained properly). This alone justifies its higher price tag and converts into a value for money product so now look at its benefits. It’s simple when you are giving better food (air) to your car to perform at its best, it is converting most profitable for you and you are still not spending much money.
