Why the Harley Heavy Breather 117ish Air Cleaner Insert is Necessary
From my experience, the Harley Heavy Breather 117ish Air Cleaner Insert is absolutely necessary for maintaining peak performance on my bike. I noticed that without a quality air cleaner insert, my engine wasn’t getting the optimal airflow it needed. This particular insert ensures that my Harley breathes better, which translates into smoother throttle response and improved fuel efficiency.
Another reason I rely on the Heavy Breather insert is its durability and filtration quality. Riding exposes the engine to dust, debris, and other particles that can cause wear over time. This insert does a fantastic job of filtering out impurities while still allowing ample airflow, protecting my engine and extending its life. For me, it’s a small upgrade that provides peace of mind and helps keep my Harley running strong.
My Buying Guides on Harley Heavy Breather 117ish Air Cleaner Insert
When I first looked into upgrading my Harley’s air intake, the Heavy Breather 117ish Air Cleaner Insert caught my attention. After some hands-on experience and research, I wanted to share what I’ve learned to help you decide if this is the right upgrade for your bike. Here’s my personal buying guide based on my journey.
Understanding What the Heavy Breather 117ish Air Cleaner Insert Is
The Heavy Breather 117ish Air Cleaner Insert is designed to replace the stock air filter on certain Harley-Davidson models, particularly those with the Milwaukee-Eight 117 engine or similar setups. It’s meant to improve airflow, enhance engine performance, and give your bike a more aggressive look and sound.
Why I Chose the 117ish Insert
I wanted better throttle response and a little more horsepower without a full intake system overhaul. This insert promised a simple bolt-on upgrade that would open up airflow while still fitting inside my existing Heavy Breather air cleaner housing — which was a big plus for me since I didn’t want to change the aesthetics too much.
Key Features to Look For
- Compatibility: Make sure the insert matches your Heavy Breather housing and your Harley model/year. Not all inserts fit every bike.
- Material Quality: I looked for durable, high-quality filter media that can handle dirt and debris while allowing ample airflow. The 117ish insert typically uses oiled cotton gauze or a similar medium.
- Ease of Installation: This insert was straightforward to install—no special tools required, which I appreciated.
- Performance Gains: While it’s not a miracle worker, I noticed a slight improvement in throttle response and engine sound after installation.
- Maintenance: Consider how easy it is to clean and re-oil the filter insert. I liked that this one was reusable and relatively simple to maintain.
Things to Keep in Mind Before Buying
- Tuning: Upgrading the air intake may require you to adjust your fuel management system or get a tuner for optimal performance and to avoid running lean.
- Legal Considerations: Depending on your location, modifications like this might affect emissions compliance or noise regulations. I checked local laws before proceeding.
- Cost vs. Benefits: The insert is moderately priced, but if you want bigger performance gains, you might need to consider a full air cleaner upgrade or additional engine mods.
My Installation Tips
I made sure my bike was cool before starting. Removing the old filter and inserting the 117ish filter was straightforward—just took a few minutes. I cleaned the area around the housing to avoid any dirt getting inside. After installation, I double-checked the seal to prevent unfiltered air leaks.
Final Thoughts
If you’re looking for a simple, effective way to boost airflow on your Harley Heavy Breather setup without drastically changing your bike’s look, the 117ish Air Cleaner Insert is a solid option. From my experience, it offers noticeable improvements with minimal fuss. Just remember to pair it with proper tuning to get the most out of your upgrade.
I hope my insights help you make a confident choice on this product!
