Things to consider before buying

right pit bike air filter

It's never an easy task to determine which air filter suits your pit bike and which one not. Even after choosing one, the filter needs to have some must-needed features to enhance the engine performance.

Those, who don’t know what an ideal pit bike air filter needs to have, must go through the following section. And if you already know, then it won’t be an unwise thing to enrich the knowledge.

  1. Choose between mesh or foam air filter.
  2. Inner diameter typically stays between 38 to 43 mm.
  3. Go for an adjustable clamp for a better fit.
  4. Overall height shouldn’t be more than 85 mm.
  5. Washable and reusable filter.
  6. Checking out the compatibility is a must.
  7. Fuel filters and carburetors as additional things.

Now you might be thinking which what does it mean by compatibility here? Well, you will get the answers below.

Air-filter design

Basically, there are two types of air filters when it comes to the design. The first one is the most common, which has a mesh filter. It can either come with carbon activated, cloth and mesh construction, or fabric mesh construction.

On the other hand, the second one has dual-foam construction. It soaks the air and filters it without requiring any mesh design.


While talking about the mesh, the most crucial aspect is to know the inner diameter. It ranges from 32 to 43 mm. On average, most filters have 38 to 40 mm of inner diameter.

The next thing is the outer diameter, which ranges from 48 to 73 mm typically. However, a quality air filter typically isn’t tall than 85 mm.

Adjustable clamp

It’s not the case that an air filter will provide a universal fit every time. Therefore, you need to go for one that is equipped with an adjustable clamp. An adjustable clamp offers adjustability from 30 to 53 mm typically.

The number varies depending on the manufacturer as well as on the inner diameter of the air filter.


Don’t you think the filter will get dirty soon after you came back from a long ride on the trails? Yes, it will. This doesn’t mean you have to take it off and throw it away.

The solution to making it reusable is to purchase one that offers easy washing with cleaner. It doesn't matter which type of filter you are buying; a good one will always have washable and reusable features.


Although we have included this crucial point down here, it’s a mandatory one. Typically, air filters are compatible with engines from 50cc to 200cc. However, each manufacturer provides information regarding bike models compatibility.

If you have gone through the products’ discussion above, you might have noticed the compatibility listings. However, a universal air filter is suitable for any bike model.

Additional inclusions

Neither spare fuel filter nor carburetor is a common thing that comes with an air filter. But both these are handy additions. It enhances the performance of the engine and provides a better service to the rider on trails.

How to clean a pit bike air filter

To enhance the engine’s performance on the trails, you need a well-functioning air filter. However, you need to maintain the quality of the filter by regular cleaning when it becomes dirty.

The problem is that many of us don’t even know the correct procedure for cleaning. I hope that the below steps will come in handy to ease the cleaning process of a dual-foam air filter.

  1. Put on a pair of latex gloves before you start.
  2. Gather a soft cloth, cleaner, a bucket of water, etc.
  3. Remove the seat belt to take out the filter easily.
  4. Now carefully take out the air filter.
  5. Please ensure no dirt and debris gets inside the air intake while removing.

  13. Place it back on the engine.

The cost of a pit bike air filter

On average, pit bike air filters cost $4 to $16. The cost differs depending on the construction quality and design. Mesh air filters are comparatively cheaper than foam air filters. One has to spend $20 or more to purchase a foam air filter.

Another thing you need to know about the cost of the air filters is that whether it comes with any additions or not. In most cases, an air filter comes as an individual item. However, if there might be an inclusion of carburetor.

Typically, a combo pack of the carburetor and air filter will cost you more than 30 bucks.  


Which is better, foam air filter or mesh air filter?

Both foam air filters and mesh air filters have distinguishing features and usability. But when it comes to affordability, long-lasting performance, and most usability, a mesh air filter is better. However, a foam air filter refines the air in a better way.

Are air filters washable?

Yes, both mesh and foam air filters are washable. The manufacturers make washable air filters to provide reusability and ensure reliable performance in the long run.

Why is an adjustable clamp necessary?

As every filter doesn’t come with a universal fit, it includes an adjustable clamp. The adjustability allows the filter to fit on various mounting holes with efficiency.
