Will ATV Run without Air Filter?

An air filter is designed to trap harmful particles from accessing your ATV engine. However, if your ATV’s air filter is dirty or clogged, limiting your riding experience, you might be tempted to eliminate it.

But will your ATV run without an air filter? Here’s why you should not ride your ATV without an air filter.

What is an air filter?

An air filter is a device that prevents dust, particles, insects, or debris from getting into the ATV engine and ensures a good mixture of air and fuel to support performance. They are usually made of synthetic paper, cotton, or foam.

What does an air filter do on ATV?

To produce sufficient power, an ATV engine needs both air and fuel. When the engine’s intake system sucks air in, there’s a need to prevent debris, dust, or insects from getting inside the engine. Air filters are meant to trap these particles to keep the engine clean. All air must pass through the air filter on the carburetor before getting into the engine.

So, will ATV run without an air filter?

Although you can run an ATV without an air filter, it’s not the best idea. The air filter plays a crucial role in your ATV and protects your engine from elements that can make it seize. Eliminating the air filter can improve performance for a short time, but this will cost you a fortune in the long run.

However, these filters get clogged over time, ruining your riding experience. This means you should remove them and clean or replace them before hitting the road again. If you run your ATV without an air filter, debris and other particles will damage your engine by mixing the oil, increasing the engine’s friction.

If the contaminated oil runs through your engine, it will destroy the engine walls, valves, rings, and cylinders. Therefore, you need an air filter to keep the engine clean and allow it to run smoothly.

Additionally, a malfunctioning air filter will harm your engine performance by affecting the turbocharger. The turbocharger takes pressurized air into your engine to enhance its performance. If it absorbs unfiltered air, you’ll notice reduced fuel economy, and if not treated, it will lead to engine seizure.

Why do people prefer running their ATVs without an air filter?

Some ATV enthusiasts prefer to ride their quads without air filters to enhance performance because the engine breathes well with an air filter blocking excessive airflows. Eliminating the air filter also makes ATVs roar louder and have great pickups. However, these gains are short-lived.

However, modern ATVs come with fuel-injected engines, so this doesn’t affect their performance. The computer regulates the air and fuel mixture; hence the engine performs the same.

Although a carbureted bike can run a bit faster without an air filter, your engine might wear out faster, especially when riding on dusty roads. Other undesirable effects include:

  • A spike in running expenses
  • Weakening your ATV
  • Excessive smoke emissions from the exhaust
  • Your ATV becomes vulnerable to polluted air

If you’re looking for superbike sounds and enhanced performance, you can use an aftermarket air filter which allows more air into the engine, thus translating to increased engine power.

How to keep your engine safe from harmful particles

Here’s how you can keep your engine safe from dust, dirt, and debris:

  • Use high-quality air filters: A high-quality air filter allows only the purest air into the engine. Therefore, ensure you get the best air filter you can find in the market. However, ensure that the air filter you choose fits in your ATV’s air filter box.
  • Clean the air filter frequently: Don’t run your ATV on a clogged air filter. A dirty air filter will lose its ability to trap all harmful particles, allowing them to ruin your engine. Additionally, a clogged air filter makes it hard for your engine to breathe, thus reducing its performance. Ensure you clean the air filter frequently and after riding on dusty trails.
  • Change the air filter regularly: Regularly changing your ATV’s air filter will prevent contaminant buildup. Besides, replacing it only takes a few minutes and is cheap. Doing so will ensure that your ATV runs on the purest air and also has a long-term performance.

How to clean your ATV air filter?

  • Choose a dirt spot to clean your air filter.
  • Get the necessary equipment, including a cleaning bucket, filter cleaner, filter oil, rubber gloves, and cleaner for the airbox.
  • Gently clean your air filter in the bucket. Ensure you use a high-quality cleaner that won’t ruin the glue that holds the foam together.
  • After the filter is spotless, leave it to dry.
  • After it’s dry, gently apply the filter oil and ensure you’ve covered every part.
  • Leave it for a few hours and clean the filter box with the sprayer cleaner. Use a clean cloth or sponge to absorb the residue.

Final Thoughts

Air filters are a must-have for any ATV. An air filter will increase your engine life, eliminate accelerated engine wear, and keep your engine safe from harmful particles. To avoid unnecessary repair costs caused by accelerated wear and tears, it’s advisable to run your ATV with an air filter.
