What Does An Air Cleaner Do For A Harley?

Air cleaners are made to help filter air particulates out of the air before the air enters the motor with the fuel. A mixture of air and fuel is needed for combustion. Only pure and clean air will enter.

This will help improve combustion greatly, the efficiency improves, and the power delivery also becomes very smooth. This will result in a smoothly running engine and performance of your vehicle. As more power is provided, your vehicle will move much more easily.

What Is The Difference Between Stage 1 And Stage 2 Air Cleaner?

A stage 1 air cleaner replaces the filter, and it can also replace the box that it is mounted in. A stage 2 cleaner. However, for example, the # AR300 – 237 will replace all of this and also has some additional equipment.

This will usually be a hose or collar with a larger diameter. The stage number will affect the air flow, as with higher stage numbers, the air flow will become better. The two-stage air filter can be used when the contaminate content level is much higher.

How Do I Remove Stock Harley 103 Air Cleaner?

You can easily remove the stock air cleaner by yourself without assistance. First, you will find the air cleaner cover bolt behind the “103” insert hidden. This will be held on with heavy Velcro.

You can easily pull it off and set it aside. It is best to use a 5/16 Allen to help remove your air cleaner cover. The cleaner can also be cleaned using lukewarm water and a mild detergent if you wish to do so.


There are a few things to consider when choosing the best air cleaner. Among these are the CADR ratings, which will determine the level of purified air when the bike is at the highest speed achievable.

You should also make sure that the filter you purchase is a high-efficiency particulate filter. A common trick for that is aiming towards the bigger ones because the bigger they are, the more effective.

Similarly, the larger the surface area is, the more dirt particles will be kept, therefore a cleaner airflow. Another consideration is the temperature resistance because if you live in a hot climate area, then getting one with higher resistance to temperature is necessary.

With all the features and considerations in mind, the most recommended, popular, and best air cleaner for Harley 103 is the K&N Engine Air Filter, which delivers remarkable performance.
