The more dirt, dust, and abrasive debris that is removed from the air entering the engine, the more efficient its performance will be and the longer it will last. Therefore, it is logical to invest in a higher quality air filter to increase engine efficiency and extend its life. Replacing a clogged air filter can improve fuel efficiency and acceleration, depending on the make and model of the car. It is recommended to replace air filters at least every 12,000 to 15,000 miles (19,000 to 24,000 km) to maintain maximum performance. So how can an air filter make such a difference? A dirty or damaged air filter limits the amount of air that enters the engine, making it work harder and consume more fuel.
As the engine needs more than 10,000 liters of oxygen to burn every liter of fuel, it is important not to restrict this airflow. If you drive frequently in very dusty conditions, it is best to reduce this interval. The best way to choose an air filter is to consult a professional who can help you select the most suitable one for your needs. Cheap air filters usually have a low MERV rating of 6 or less, while expensive air filters can have a MERV rating of up to 13. Dirty or damaged air filters reduce airflow to the engine, disrupting the car's air-fuel balance. If you have asthma or allergies, it is especially important to choose an air filter with a high MERV rating so that you can remove as many harmful particles from the air as possible. To measure the airflow of a particular air filter, you'll need two pressure gauges and accessories to pierce the air intake before and after installing the filter. Cheap air filters don't last as long, are less efficient at trapping particles and have a smaller surface area to filter.
A high-performance air filter is more technically known as a high-flow air filter, which explains how it differs from a normal air filter. It is important to note that high-performance air filters are considered a modification and can void the warranty if you have a new vehicle that is still within the warranty period. Expensive car air filters are made of higher quality materials, last longer, trap particles more efficiently and have a larger surface area to filter. On the other hand, a K&N air filter installed in my Kawasaki Concours not only gave me that cold growl when accelerating, but I also noticed a smoother idle speed and a small increase in top speed performance above 7,000 rpm. In conclusion, investing in an expensive car air filter can make a difference in terms of engine efficiency and performance. It is important to consult with an expert before making any decisions about which type of filter is best for your vehicle.
Additionally, if you suffer from asthma or allergies, it is essential to choose an air filter with a high MERV rating so that you can remove as many harmful particles from the air as possible.
