This best air filtration system from ATV Parts is one of the most versatile air filters out there as it can be used for different types of engines. In terms of looks, this one looks a bit like the Poweka filter that we’ve reviewed earlier. However, there are only a few similarities between them. 

These will fit PZ19, PZ16, and PZ20 carburetors perfectly. They are specially made for ATVs, Go Karts, and dirt bikes. These will be best for engines of 50, 70, 90, 110, and 125ccs.

However, one drawback is that these are designed for models made in China. If your ATV isn’t Chinese, then these might not support it. 

So, do we recommend these? Yes, if you’re a person who’s running on the stock air filters provided by the Chinese ATV or dirt bike manufacturers, then you should really consider switching to these. 

These air filters will not only perform better than the stock ones, but they will last longer as well. They are much better in terms of airflow as well. If your engine is overheating despite being new, then upgrading to these will help you. 

Another problem that many people face with these is the fit. These are a bit bulkier than most of the other filters that you can find on the market. This is why there’s always a chance of them not fitting. 

Pros

  • Helps customize Chinese ATVs, dirt bikes, and Go Karts.
  • 35mm diameter allows great airflow

Moreover, it comes with a neck that’s angled at 45 degrees. There’s also a splash-proof cover that will keep the filter safe from water and mud. 

Filtration in this product is done using a stainless steel mesh system. This block is very thick, and it has the capability of removing most of the dust and sand from the air passing into your bike.

However, you’ll need to clean it once in a while, or the airflow will reduce to some extent. 

One of the things that makes these filters one of the best is that they are built following strict quality standards. The chances of getting a faulty unit for yourself are very rare, as all of these units are tested before they reach the market. 

This is why we highly recommend these filters.

The HIFROM air filtration system is one of the most versatile and universal systems out there, and it’s also one of the few that provides maximum airflow. Essentially, these units were built for airflow. However, that doesn’t mean that they won’t block any dirt.

You can get these units in three different diameter sizes, which are 35mm, 42mm, and 48mm. The length of these units stands at 145mm, which makes them not too big nor too small. 

If you’re a person who experiences a heated-up engine and thermal throttling after a few minutes of driving, then perhaps the air filter installed in your vehicle is choking it. 

This is where the HIFROM air filters come in. These filters are built to provide quality airflow. With the added boost in airflow, your engine will be able to run a long time without facing thermal throttling. 

Another amazing feature is that you’ll be able to get professional help if you purchase these filters. If you’ve never installed a filter of this type before, then this can help you out. If you’re stuck with something, getting help from professionals will solve your problem.

7. 38mm Bent Angled Foam Air Filter

Finally, we have the Quifadong air filters. These best dirt bike air filters come with a diameter of 38mm. Although this diameter is most widely found amongst suitable vehicles, it’s a bit disappointing that there are no other sizes. 

These offer a bent and angled output. This angle will help you, especially if the smoke output is upward-facing your vehicle. These are built especially for dirt bikes and ATVs. However, you’ll be able to install them on Go Karts as well. 

The outer shell is made of foams that will capture dirt and debris from the environment and prevent them from reaching the engines. Also, the filtration foam is very thick and is capable of purifying the air to a great extent. 

Even though these are very well made, it’s a pity that you won’t be able to use them on any vehicle. Rather, they are built especially for vehicles that were made in China. 

While that might be a limiting factor to some, this is also good news for people who own Chinese vehicles. There aren’t many high-quality air filters that can be equipped on Chinese vehicles, and this one serves as a great addition to that limited inventory. 

Pros

  • 38mm diameter ensures sufficient airflow 
  • Thick foam padding offers quality filtration
  • A great extension for Chinese vehicles
  • Bent angle for more convenient usage

Cons

  • Can be used on Chinese vehicles only
  • Some cases of faulty product were seen

Things to Consider Before Buying Dirt Bike Air Filter

It’s okay if you’re confused about which product is suitable for you after seeing the ones listed above. There are many options to choose from, and all of them offer something unique.

This section will highlight the factors that you’ll need to consider for getting the most suitable air filter for your dirt bike. 

Ease of Usage

Don’t get a cheaper filter if it’s hard to install. There are air filters for dirt bikes that can be installed in five minutes, and there are those that require hours for installation. 

Then again, there are filters that might seem too tight or too loose. We suggest you look out for such products. Installing these will never provide a long-term experience for you. 

Filtration Capabilities

Filtration is the major purpose for which you’ll be getting an air filter in the very first place. This is why we recommend focusing on this factor the most. There are different types of filtration systems out there. 

Some filters come with OEM papers, foams, cotton gauze, and even stainless steel mesh. Each of them offers a different experience, and we recommend checking out which one of them will be the perfect choice for you. 

While some of these products will be able to purify the air to the purest form, they might also reduce the airflow significantly, which will definitely hold you back.

Airflow

Speaking of airflow, we come to another major issue that you must address while looking for the right product for yourself. While filtration is important, it’s also important to keep the airflow to a healthy level. 

If the airflow reduces below a certain limit, then your engine will end up overheating, and you’ll slow down due to thermal throttling. This is why we highly recommend that you balance filtration and airflow. 

Maintenance

You don’t want a filter that needs to be washed every day, as that wouldn’t be practical. This is why we highly recommend getting a filter that doesn’t require regular cleaning, at least. 

If the filter provides you great support and needs to be cleaned only occasionally, then that one’s perfect for you.

Durability

Finally, you’ll need to consider the durability of the filter. If that filter can’t last a considerable amount of time, then there’s no point in spending on that. 

There are many filters that come with stainless steel build. We highly recommend going for these as they are very long-lasting. 

How Often Should I Clean My Dirt Bike Air Filter?

To be honest, there’s no specific period after which you need to clean the air filter. In fact, it completely depends on one simple fact, whether the filter needs any cleaning or not!

There are many filters that require regular maintenance, and there are those that you need to clean occasionally. Now, we’ll talk about some factors that’ll help you determine when the filter needs to be cleaned. 

The first red flag is a dirty filter, and this is the most obvious one. If you find that the filter is dirty, then you should definitely clean that up. This will help it function like a brand new unit again. However, this one’s not so practical as you won’t be checking the filter all the time. 

Another flag is reduced mileage. If you find that your vehicle isn’t going as far as it’s supposed to go on a specific amount of fuel, then it’s a possibility that a dirty filter is reducing its mileage.

Other than these, there are some subtle things such as slow acceleration, engine not starting, and weird noises from the engine that can denote whether a filter is dirty or not.

Final Words

Choosing the best dirt bike air filter can definitely be a challenge, but not if you follow this guide properly. You’ll be able to come to a reasonable decision with what you’ve learned from this till now. 

We strongly suggest that you pick a product from the list above, and we’re confident that you won’t find any better product other than these.
