Does A High Flow Air Filter Make Difference?

First learn, what does an air filter do?

A stock filter filters polluted air particles to deliver non-toxic air to the engine for better combustion. A high flow air intake or high-performance filter, the way you call it, also does that. The difference is, it does it better. Here’re some of the advantages of using high flow air cleaners over conventional ones.

Now learn about the high flow air filter:

High flow filters allow more air to pass into the engine easily resulting in better combustion. This improves its horsepower and performance greatly. Typically, high flow filters increase your bike’s horsepower by 5-10HP, whereas, high-end air cleaners increase it up to 25HP.   

High-quality air intake doesn’t only result in improving the horsepower of your Harley, it also helps the engine to be more efficient. When better combustion occurs, the engine doesn’t need to work much while accelerating and maintaining high speeds. This allows the engine not to use much gasoline which makes it fuel-efficient. Even though fuel efficiency depends on many factors, better air intake improves the gas mileage by 10-15%.

Another benefit of using a high-performance Harley-Davidson filter is, you don’t have to change it every year, unlike regular filters. The only thing you need to clean the filter in about every two years or so. This is because the high-quality filter elements don’t get clogged easily which allows them to run for more miles without being cleaned or changed.

Last but not the least, even though the high-performance filters seem to be expensive, they usually end up being an affordable option. This is because of their long service lives and reusability.

How to Choose the Best Air Filter For Harley Davidson?

If you’re buying an air filter for the first time, you may find it a bit tricky. This is because you’ll find lots of similar products each claiming to be the best yet cost different prices.

You need to find out the right air filter that works with your Harley. To assist you with that, I bring a detailed buying guide that meets all your queries and helps you get the best air cleaners for your ride.

Types of Air Filter

There’re mainly three types of air filters namely, paper air filter, foam air filter, and cotton air filter.

The paper filter is the most commonly used type, thanks to its cheap price and availability. Even though the name suggests using paper as a material, they actually are made of a thick cellulose layer that is mixed with other materials. It has sufficient pores to be breathable even when high intake is taken from the engine. However, the inexpensive type of air filter has a limited life expectancy. You might need to change it frequently.

The foam air filter, on the other hand, is an expensive option that can be used for a long time if maintained properly. They also perform better if you want high airflow from the filter. Foam air filters are mostly used on off-road bikes.

The cotton air filter is another expensive air cleaner type that isn’t widely available. They also provide a long working period in which they can be washed and reused again.

Shape & Dimensions

The shape isn’t that important unless you’re too choosy about it. However, as the filter is placed outside of the engine, its dimension needs to be accurate for the best fitment.

All you need to do is to measure the flange, the height, and the width of the base. Knowing these dimensions will help you to search for the filter that fits on your bike’s engine. Again, if the bike comes with an OEM round tapered air cleaner, I recommend looking for a similar aftermarket option.

Many people love to have a custom Harley air cleaner cover so that the bike looks interesting.

Durability

Even though durability is almost a dying issue while searching for an air filter cover, there’re still some cheap filters that claim to be high-performance air purifiers. There’s a high possibility of tearing of the filter when you try to clean and re-use them.

The point is, when you try to save some bucks, you might eventually need to spend more money on changing air cleaners frequently. There’re obviously exceptions like the budget option on my list that deliver the best return for the money. So, make sure the high flow air cleaner for Harley Davidson that you choose is durable enough to withstand heavy usage and run longer.

Performance

Keep a track of the performance the manufacturers claim to have. Most manufacturers don’t usually show third-party performance test results. Screamin Eagle Heavy Breather Air Cleaner, K&N is an exception to that.

Oiled foam purifiers are known to allow additional airflow to the engine. That’s why they are mostly used on performance bikes such as sports bikes and off-road bikes.

Some paper filters also claim to be highly efficient than the OEM filter. You need to make sure they really are capable of increasing torque rather than falling for cheap advertisement.

Ease of Installation

The installation of the best air cleaner for Harley Davidson is one of the easiest tasks to do. However, things get messy when you get a filter without pre-oiled. It takes a bit long time and dedication. So, look for the pre-oil filter which can be easily installed within a few minutes.

Another thing to take care of is the time to be replaced or cleaned. Most aftermarket filters provide a certain mileage after which you must have to clean or replace them. However, I recommend cleaning them even before you reach up to that mileage, especially if you live in a polluted locality.  

Frequently Asked Questions

How often should I change my Harley air filter?

The period mainly depends on the mileage you’ve covered with an air filter. Different manufactures offer different mileage after which you should either clean or replace the filter. You’ll get the information in the manual. However, if you are from a polluted locality, you may need to change the filter even before.

Can’t I Just Run My Motor Without A Filter for Better Performance?

You can run the bike without an air filter but that’d greatly damage the engine’s performance and longevity as it makes the engine exposed to all harmful grit and intake inhale dust.

Do performance air filters actually work?

Yes, the best aftermarket Harley air cleaner actually improves the engine performance. however, the improvement will vary from one filter to another depending on their price as high-priced filters usually work better than the cheapest air filters. It also depends on your driving pattern largely.

Conclusion

Air cleaners for Harleys play a great role to get the maximum performance from the bike which is it famous for. A high flow air filter for Harley Davidson not only improves its overall performance but also increases the engine’s lifetime. I hope the article helps you find the best air filter for your bike.
