Crafted from premium, durable materials, this cover is more than just a protective casing it s a precision-fitted solution that enhances airflow efficiency while maintaining a sleek, understated aesthetic.

### **Pros and Cons of buying a Cycle MN/2JJ6S Stealth Air Cleaner Cover for a 1999-2009 Harley-Davidson FXDL Dyna TZ (MN/2JJ6)**

1. **Improved Aesthetics** The Stealth air cleaner cover replaces the stock, utilitarian design with a sleeker, more aggressive look that enhances the bike s sporty appearance. It blends well with the Dyna TZ s aggressive styling, giving it a more modern and custom feel.

2. **Better Airflow and Performance** Unlike some aftermarket covers that restrict airflow, the Cycle MN/2JJ6S is designed to maintain or even slightly improve airflow to the engine while providing a cleaner, more streamlined look. This helps prevent clogging from debris while keeping the stock air intake system functional.

3. **Durability and Quality** Cycle Manufacturing is known for producing high-quality, well-engineered parts. The Stealth cover is made from durable materials that resist warping, cracking, or degradation over time, especially when compared to cheaper aftermarket alternatives.

4. **Easy Installation** The cover is designed to fit the MN/2JJ6 engine family (including the FXDL Dyna TZ) without extensive modifications. It typically requires minimal tools and can be installed in under an hour, making it a straightforward upgrade for DIYers.

5. **Protection from Elements** While the stock air intake is exposed, the Stealth cover provides a slight barrier against dust, road debris, and minor water ingress, helping to prolong the life of the air filter and intake system.

6. **Compatibility with Other Mods** If you plan to add an aftermarket air intake (like a K&N or Spidertop), the Stealth cover can serve as a transitional or aesthetic piece before or after installing a full intake system.

7. **Positive Community Reception** Many Harley-Davidson owners, particularly those in the Dyna and sport-touring scene, praise the Stealth cover for its balance of function and style. It s a popular choice among customizers who want a subtle yet noticeable upgrade.

---

1. **Cost** Compared to the stock air cleaner, the Cycle MN/2JJ6S is a premium product. Pricing typically ranges between **$150 $250**, depending on the retailer and any additional accessories (e.g., gaskets, mounting hardware). This may be a significant investment for riders on a tight budget.

2. **Minimal Performance Gain** While the cover doesn t restrict airflow, it doesn t significantly improve horsepower or throttle response. If your primary goal is performance, you may need to pair this with an aftermarket air intake or exhaust system for noticeable gains.

3. **Potential for Misalignment** If not installed correctly, the cover could interfere with the stock air intake or throttle body, leading to airflow restrictions or even damage. Precision is required during installation to ensure a proper seal and alignment.

4. **Limited Customization** Unlike some aftermarket intakes that allow for color changes or additional modifications, the Stealth cover is a one-size-fits-all design. If you want a unique look (e.g., carbon fiber, custom paint), you ll need to explore other options.

5. **Weight Addition** While not significant, the cover adds a small amount of weight to the front of the bike compared to the stock setup. This is negligible for most riders but could be a consideration for those prioritizing minimal weight.

6. **Maintenance Requirements** The cover itself doesn t require frequent maintenance, but the air filter inside must still be cleaned or replaced regularly (every 5,000 10,000 miles, depending on riding conditions). Neglecting this could negate the benefits of the cover.

7. **Potential for Aftermarket Conflicts** If you later install a full aftermarket air intake (e.g., a cold-air system), the Stealth cover may no longer be compatible or functional. Some riders choose to remove it once they upgrade their intake.

---

The **Cycle MN/2JJ6S Stealth Air Cleaner Cover** is an excellent choice for Harley-Davidson FXDL Dyna TZ owners who want to enhance their bike s appearance without sacrificing performance or airflow. It strikes a balance between aesthetics and functionality, offering a high-quality, durable upgrade that integrates seamlessly with the stock engine setup. While it doesn t provide dramatic performance gains, it serves as a practical and stylish intermediate step for riders who may eventually pursue more aggressive modifications.

For riders who prioritize **look over performance**, the Stealth cover is a worthwhile investment. For those focused on **raw power**, it s a useful aesthetic upgrade but may need to be paired with additional mods (like an aftermarket intake or exhaust) to see meaningful gains.
