Factors You Need to Consider When Buying The Best Air Intake For Harley Davidson

Power

One of the primary reasons you may be looking to buy an air filter for your Harley Davidson is to increase the performance of your bike.

Different air filters will have different effects on the performance.

Depending on the quality, it could drastically improve the efficiency of your bike, or an air filter could even reduce the performance if it’s low quality.

Because of this, one of the main things you need to look out for is how much an air filter affects your Harley-Davidsons performance.

If you want to increase your bike’s power drastically, you’ll want to opt for an air filter that does that.

Although, if you aren’t too concerned with optimizing your bike and just want a nice boost to the performance, then the power isn’t as much of a factor for you.

Installation

Some air intakes are designed to make the installation process as easy and seamless as possible. Although, some are not.

If you want to install your air intake yourself, you’ll need to make sure that you can install whatever intake you choose.

Because of this, unless you are an experienced mechanic, it may be best to opt for an air intake that’s simple to install.

On the other hand, you could always go to a professional to get your air intake installed on your Harley Davidson, which completely negates the installation process.

Quality

The quality of an air filter is a crucial aspect you need to consider.

Lower-quality air intakes will not last as long as high-quality ones. They also possess other negative traits, such as giving only a negatable increase in performance or even damaging your bike.

It’s always better to go for higher quality air intakes to avoid the problems we listed above.

Although, if you don’t use your Harley much, then you may not need to go for the crème de la crème.

Emissions

One of the most potentially serious factors you need to consider is the emissions an air filter gives off.

Not only is giving off a lot of emissions bad for the environment, but it can also face criminal repercussions in specific locations.

It’s of the utmost importance to check if the air filter you plan to get is legal wherever you plan to drive it.

To check if an air filter is legal where you are situated, do a quick google search about the regulations around your area.

For some of the more popular air filters, you could even type the specific filter into google and get results quickly.

Finally, if either option doesn’t work, you could go to a local automotive store and ask.

Looks

A factor that is often ignored is the visual component of an air filter. No one wants to get an air filter that reduces the looks of their bike.

Instead, you should make sure the air intake you purchase improves the aesthetics of your bike.

Of course, looks are always subjective. Because of this, there are many different looks and styles to ensure that there is a lookout there for everybody.

Many people ignore this factor and don’t even think about how a particular air filter will look on their Harley.

Instead, they go for an air filter that improves the performance and efficiency the most.

However, an air filter that looks bad on your bike will quickly become stale.

If you don’t like the look of your Harley, this can be a big issue.

You may find that even though the air filter you chose gives you the best performance, it takes away from the looks, which leads you to buy a new air intake rendering the previous purchase worthless.

Size

The size of an air intake matters for a few reasons. For one, not every Harley air intake will fit on every motorbike.

This means that getting an air filter that is the wrong size will be a complete waste of your time as it will be unusable.

In addition, even if an air filter does fit, it may still look too large or small on your bike.

To remedy this, it’s always vital to check if an air intake is suitable for your Harley Davidson.

Companies will usually state what bikes their air filter will fit, so make sure to look out for it and ensure your bike is compatible.
