Types of Motorcycle Air Filters
As an important component of the motorcycle engine, the motorcycle air filter’s main function is to filter dust and impurities in the air to ensure that the air entering the engine is clean, thereby protecting the normal operation of the engine. With the continuous development of motorcycle technology, many different types of motorcycle air filters have appeared on the market to meet the needs of different models and usage environments. Several common motorcycle air filter types are detailed below.
Paper pleat air filter
Paper-pleated air filter, also known as paper-pleated air filter, is the most common type found on motorcycles. It uses a paper filter element to block dust and impurities in the air through the fiber structure of the paper material. This kind of filter has the characteristics of simple structure, low manufacturing cost and good filtration effect. However, the paper filter element cannot be cleaned, and once it is clogged or damaged, it needs to be replaced with a new one. Therefore, during use, it is necessary to regularly check the status of the filter element and replace it in time to ensure the filtration effect.
Foam air filter
Foam air filters use sponge or foam materials as the filter element to capture dust and impurities in the air through the viscosity of the filter element surface. Unlike paper dry filters, sponge foam wet filters can be cleaned and reused. When the filter element is clogged, its filtration performance can be restored by cleaning. This kind of filter is suitable for dusty environments and can protect the engine more effectively. However, it should be noted that when cleaning the filter, make sure to dry it thoroughly to avoid residual moisture affecting the filtration effect.
Cotton gauze air filter
Cotton yarn air filter is a motorcycle air filter made of cotton yarn material. Being able to absorb oil mist and harmful gases in the air makes cotton air filters more adaptable in some special environments, such as areas with high pollution or high dust. However, the filtration effect of cotton air filters may be slightly inferior to some modern high-efficiency filters. In harsh environments or areas with high pollution, it may be necessary to choose a more efficient filter to protect the engine.
The filtration effect mainly depends on the fiber density and filtration area of the cotton yarn material. The finer the fiber of the cotton gauze material, the larger the filtering area, and the better the filtering effect.
In addition to the above common types of motorcycle air filters, there are also some specially designed filters, such as centrifugal air filters, composite air filters, etc. These filters usually have more complex structures and filtration mechanisms and are suitable for specific working environments and vehicle models.
When choosing a motorcycle air filter, you need to comprehensively consider it based on the model, usage environment, and personal needs. For general city riding or on-road motorcycles, paper dry air filters are often an affordable and effective option. Motorcycles operating in dusty or harsh environments may need to choose sponge foam wet or oil-based air filters to provide better filtration effects. At the same time, no matter what type of filter is used, the filter element needs to be inspected and replaced regularly to ensure its normal operation and protect the engine from wear and tear.
Symptoms of Bad Air Filters
An air filter filled with dirt can quickly turn into a bad/defective air filter. Here are some signs that it’s been too long since you’ve had a much-needed air filter cleaning:
- Unusual dark color (the color gradually gets darker the more dirt accumulates)
- Acceleration is noticeably poorer
- Reduced fuel economy
- Insufficient (or reduced) power output
- The engine makes strange noises
- Performance issues (misfire, engine stall or failure, rough idle)
- Activate check engine light
- The exhaust pipe emits black smoke or glows
- Strong gasoline/fuel smell
How often to clean your air filter?
How often you clean your motorcycle air filter depends on a variety of factors, including the type of motorcycle, the environment in which it is used, and the material and design of the air filter.
On scooters, the air filter is located lower and is more likely to get dirty. It is recommended to clean it every 2000 kilometers. When it is found that the air filter element is dusty, severely clogged, or loses its filtering effect, it should be replaced with a new filter element in time.
For straddle bikes and curved beam bikes, if there is a lot of dust in the air, it is recommended to check and clean them every 5,000 kilometers or so. In an environment with relatively clean air, the cleaning interval can be appropriately extended.
| Type of Motorcycle | Frequency (Approximate) |
|---|---|
| Road racers | Every 2,500 – 10,000 miles |
| Off-road/trail riders | Every ride (twice every ride during summer) |
| MX/adventure bikes | Every ride up to 10,000 miles |
| Sportbikes | Every 2,500 – 10,000 miles |
| Dirt bikes | Every 50,000 miles for casual riders |

| Scooters | Every 2,500 – 10,000 miles |
| Full-faired/track bikes | Every ride up to 10,000 miles |
| Performance bikes | Every ride up to 10,000 miles |
| Motorcycles in general | 2,500 – 20,000 miles |
FAQ About Motorcycle Air Filter
The air filter on a motorcycle plays a vital role in ensuring the smooth and efficient operation of the engine. The following are the main functions of a motorcycle air filter:
Blocks Dust and Debris: The air filter effectively blocks dust, dirt, and other debris from entering the engine. When a motorcycle is running, a large amount of air is sucked into the engine for combustion. Without a filter, the air would carry various impurities that could damage the internal structure of the engine.
Protects engine components: By filtering out contaminants, air filters help protect sensitive engine components, such as cylinders, pistons, and valves, from wear and tear. This extends the life of your engine and keeps it running smoothly.
Maintains optimal air-fuel ratio: The air filter also helps maintain optimal air-fuel ratio within the engine. This ratio is critical for efficient combustion, which in turn affects the motorcycle’s power output and fuel economy.
Improved Performance: A clean and effective air filter allows your engine to breathe more freely, improving performance. A clogged or dirty air filter can restrict airflow and reduce your engine’s power output.
MPM recommends that it is important to clean or replace the air filter regularly to ensure it continues to perform its function effectively. A dirty or clogged air filter can lead to reduced engine power, increased fuel consumption, and even damage to the engine in the long run.

Yes, motorcycle air filters do affect your exhaust system.
The main function of the motorcycle air filter is to filter the air entering the engine, remove dust, sand and other impurities, and ensure that the air entering the combustion chamber of the cylinder block is clean. If the air filter has not been cleaned or replaced for a long time, the filter element may become clogged, resulting in poor engine air intake, insufficient air intake, and insufficient gasoline combustion. This will not only affect the power and performance of the engine, leading to increased fuel consumption, insufficient power, worsened emissions and other problems, but may also allow some unburned impurities to enter the exhaust system.
When these impurities are discharged through the exhaust system, they may adhere to the inner wall of the exhaust pipe, causing blockage or corrosion of the exhaust pipe and affecting the exhaust effect. Over the long term, it may also cause wear and damage to exhaust system components, which in turn affects the overall performance and life of the motorcycle.
Therefore, regular cleaning and replacement of your motorcycle air filter is essential to protect both your engine and exhaust system. It is recommended that vehicle owners regularly check and replace the air filter according to the usage and environment of the motorcycle to ensure the normal operation and extended service life of the engine and exhaust system.
