Hurricane Air Filter Review for Harley-Davidson 117 (Stage 1 Setup)

Endless learning.

Riding Impressions After the Intake Change

I knew I was going for a full Stage 1 setup the moment I got my Harley Davidson Low Rider S 117. It wasn’t a question of if, but how and in what order. I started with a tuner and a full system exhaust, partly because they’re the most obvious upgrades, and partly because the stock air filter looked at least visually like it already flowed well. The shape suggested performance. It felt like something I could revisit later. As it turns out, that assumption became one of the more interesting lessons in this build.

Hurricane Air Filters — Thai-Made Performance for Your Harley-Davidson 117

When you’re tuning a Harley-Davidson engine (or any bike for that matter) to Stage 1 levels with exhaust upgrades and ECU tuning optimizing engine breathing becomes one of the most effective and affordable performance enhancements you can make. There are plenty of aftermarket choices and one common widely use brand is K&N. A friend introduced me to Hurricane air filter series, which are engineered and manufactured in Thailand for high-performance motorcycle and cars.

What Hurricane Air Filters Are

Hurricane produces aftermarket motorcycle air filters designed to improve on typical OEM paper elements by offering higher airflow, longer service life, and reusable design. The lineup generally includes:

🛠️ Cloth (cotton) filters — multi-layer gauze that boosts airflow while still trapping fine particles.
🛠️ Stainless steel mesh filters — a more durable option with finer filtration and longer lifespan.

Both are washable and reusable, meaning you clean and reinstall rather than replace them as you would with stock filters.

A Stage 1 setup on a Harley-Davidson typically includes:

• Free-flowing exhaust system

• ECU tune to support increased airflow

• Intake enhancements

In this context, the air filter plays a critical role in supporting the higher air demands of the engine. A high-flow filter like Hurricane can help maximize the benefits of your Stage 1 tune by reducing intake restriction and helping the engine inhale cleaner air more efficiently

Potential Downsides & Real-World Considerations

⚠️ 1. Real-World Gains Are Often Modest

While the claimed horsepower increases sound impressive on paper, many riders find on actual bikes especially heavy cruisers like the Harley 117 the real gains are more subtle than the percentage numbers suggest without the right matching tune. Increased airflow alone doesn't guarantee power unless the ECU is calibrated to use it.

🧽 2. Maintenance Is Required

Washable filters must be cared for regularly dust and debris reduce performance if left uncleaned. This means incorporating cleaning into your regular service interval (for example at each major service).

🔍 3. Filtration vs. Flow Trade-Off

Performance filters often lean toward higher airflow at the trade-off of trapping extremely fine particles. If you ride in very dusty environments, you need to be diligent about cleaning to avoid increased engine wear.

⚙️ 4. Fitment & Compatibility

Hurricane filters are available in a variety of model-specific versions. You will unlikely have trouble finding the right fitment for your Harley’s intake system.

🔧 5. Tuning Integration

To maximize the benefit of a high-flow air filter and avoid lean conditions, a proper ECU tune or mapping session is highly recommended as part of your Stage 1 setup. Do note that the Milwaukee 8 engine are tune to run a little lean straight out of factory.

How Hurricane Compares to Other Filters

Compared with other popular high-flow filters (like K&N), Hurricane’s stainless design also offers washable durability and stable airflow without oil coatings. One of the perks of it being stainless steel is that the chances of damaging it while cleaning is close to zero.

Final Thoughts: Value for the Harley-Davidson 117

For riders who want a performance-oriented, reusable air filter that complements exhaust and ECU upgrades, Hurricane filters are a solid choice offering improved airflow, long lifespan, and potential performance and economy benefits.

If you pair the filter with a Stage 1 tuning strategy proper fueling maps and regular maintenance Hurricane can be a cost effective component in the long run as it can last easily 100,000 KM before being replaced. This is of course subject to how expose the filter is to stones and other small debris.
