Are Sponge Filters Harmful for Your Vehicle?

This is a common question that comes to users' minds when buying a performance filter. Are sponge filters harmful? Will it damage my engine?

Contrary to popular belief, dry type sponge filters are not harmful to your vehicle. While this filter allows your vehicle to take in more air, it also filters the air better and ensures that cleaner air reaches the engine. This process is important for the 'rich fuel mixture' in the engine. This is why the performance increase in your vehicle when you switch to the performance filter. The turbocharger in turbo vehicles does exactly this. It increases performance by providing extra air to the engine.

There are also oil-type performance filters that require extra lubrication, which can be troublesome for your vehicle. The filter is lubricated before being installed in the vehicle. If you apply too much oil, oil may leak to the sensors and other electronic devices and malfunction may occur. ( The filters in our company are dry type. They do not require lubrication .)

Recently, extra sponge has been added to paper filters. The reason for this is that paper filters are insufficient to filter the air, and when an area of ​​the paper filter wears out, the air is taken into the engine from that area continuously and without filtering at all.

In these 2 pictures you can see that normal paper filters are now produced as sponge type.

In the picture below, you can see a paper filter without sponge. A filter that is worn out from one area will now draw all the air from the marked areas into the engine without filtering it at all. This is a situation that we do not want for our vehicles and that damages the engine.

We understand from all this that it is important for the air to flow cleanly and uninterruptedly to the engine. Since paper filters do not provide this alone, large filter manufacturers are forced to add extra sponge under the paper. Based on this, we can understand that paper filters do not pose a danger to the engine.

Good and high performance rides.
