Harley Davidson motorcycles have a long-standing reputation for being powerful, loud, and iconic. The bikes have a unique sound and style, and they’re a favorite of motorcycle enthusiasts around the world. One way to improve the performance and sound of your Harley is by installing a stage 1 air cleaner. In this article, we’ll discuss what a stage 1 air cleaner is, why you need one, and some of the best options available.
What is a Stage 1 Air Cleaner?
A stage 1 air cleaner is an aftermarket air intake system that replaces the stock air filter and housing on your Harley Davidson motorcycle. The stage 1 air cleaner is designed to allow more air to flow into the engine, which improves performance and throttle response. It’s also a necessary upgrade if you plan on installing other performance upgrades such as exhaust pipes and tuning modules.
Why do You Need a Stage 1 Air Cleaner?
The stock air intake on a Harley Davidson motorcycle is designed to be quiet and efficient, but it’s not optimized for performance. A stage 1 air cleaner allows more air to flow into the engine, which increases horsepower and torque. It also improves throttle response and can give your Harley a more aggressive sound. Additionally, if you plan on installing other performance upgrades, a stage 1 air cleaner is a necessary first step.

What is the difference between stage 1 and stage 2 air cleaner?
The main difference between a stage 1 and stage 2 air cleaner is the level of performance improvement. A stage 1 air cleaner is an aftermarket air intake system that replaces the stock air filter and housing on your motorcycle to allow more air to flow into the engine, which improves performance and throttle response. A stage 2 air cleaner typically includes additional modifications to the intake system, such as larger throttle bodies or high-flow fuel injectors, to provide even greater performance gains.
Do I need to tune my Harley if I add an air cleaner?
Yes, it is recommended to tune your Harley if you add an air cleaner. The increased airflow from the air cleaner can cause a lean condition, which means there is too much air and not enough fuel in the combustion process. This can lead to engine damage over time. Tuning your Harley with a fuel management system or by re-mapping the ECU will ensure that the air/fuel ratio is optimized for the new air cleaner and any other performance upgrades you have installed.
How do you clean a Harley Davidson Stage 1 air filter?
To clean a Harley Davidson Stage 1 air filter, first, remove the filter from the housing. Next, gently tap the filter to remove any loose dirt or debris. Then, use a mild soap and warm water to clean the filter. Rinse the filter thoroughly and allow it to air dry completely before re-installing it. It’s also recommended to re-oil the filter using a high-quality air filter oil before re-installing it in the motorcycle.
Conclusion
If you want to improve the performance and sound of your Harley Davidson motorcycle, a stage 1 air cleaner is a necessary upgrade. The Arlen Ness Big Sucker, K&N Blackhawk Induction Air Intake System, S&S Stealth Air Cleaner Kit, and Vance & Hines VO2 Air Intake are all excellent options to consider. Whichever air cleaner you choose, make sure it’s compatible with your bike’s make and model and meets your specific performance goals.
