Review ARLEN NESS Mn/b0ax Inverted Series Air Cleaner Kit Harley Davidson Fxdls Pj fits 2017
The **Arlen Ness MN/B0AX Inverted Air Cleaner Kit** is a meticulously engineered upgrade designed to enhance both the performance and reliability of the **2017 Harley-Davidson FXDL Sportster 1200 (PJ)**, transforming its air intake system into a high-flow, high-efficiency marvel. This kit replaces the stock air cleaner with a **fully inverted, high-capacity filter assembly** that not only improves airflow but also significantly reduces intake restriction, allowing the engine to breathe more freely under all conditions. Crafted from premium materials, the inverted design ensures that the filter media remains clean and effective for longer periods, even in dusty or dirty environments, by preventing debris from settling on the filter surface. The kit includes a **high-quality, high-flow filter element** that maintains optimal airflow while still providing exceptional filtration, protecting the engine from contaminants that could otherwise cause wear or damage. The installation process is straightforward, with the kit featuring a **direct-fit design** that requires minimal modification to the stock setup, making it an ideal choice for riders who want enhanced performance without the hassle of extensive fabrication. Beyond its performance benefits, the Arlen Ness kit also contributes to a cleaner, quieter intake sound, giving the FXDL a more refined and aggressive exhaust note. Whether cruising on the highway or navigating tight city streets, this air cleaner kit delivers a noticeable improvement in throttle response, power delivery, and overall engine efficiency, making it a must-have accessory for any Sportster enthusiast looking to unlock the full potential of their bike.
### **Pros and Cons of the Arlen Ness MN/B0AX Inverted Air Cleaner Kit for a 2017 Harley-Davidson FXDL Sportster**
#### **Pros:**1. **Improved Airflow and Horsepower** The inverted design reduces air restriction compared to stock air cleaners, allowing for better airflow into the engine. Many riders report noticeable gains in throttle response and low-end torque, especially in a naturally aspirated Sportster like the FXDL.
2. **Enhanced Cooling** The inverted orientation helps keep the air cleaner cooler, reducing the risk of heat buildup that can degrade oil and restrict airflow in high-performance applications.
3. **Easier Installation** The kit is designed for straightforward installation, often requiring minimal modifications to the stock setup. It typically includes all necessary gaskets, clamps, and mounting hardware.
4. **Durability and Reliability** Arlen Ness is a well-regarded brand in the aftermarket performance community, known for producing high-quality, long-lasting components. The inverted design is less prone to oil leaks and contamination than some alternative setups.
5. **Compatibility with Stock and Modded Engines** Works well with stock engines and can also pair with performance upgrades like cold air intakes, exhaust systems, or ECU tuning for further gains.
6. **Reduced Backpressure** By eliminating the restrictive stock air cleaner s design, the inverted unit helps maintain consistent airflow, which can improve fuel efficiency and reduce engine strain.
7. **Aesthetic Appeal** The sleek, modern look of the inverted air cleaner can enhance the bike s appearance, especially if paired with other performance upgrades.
---
#### **Cons:**1. **Potential for Oil Leaks** While less common than with some other inverted designs, improper installation or a faulty gasket can lead to oil seeping into the air cleaner, reducing its effectiveness and causing engine contamination.
2. **Requires Clean Air Filter** Unlike stock setups that may tolerate slightly dirty filters, an inverted air cleaner demands a clean, high-quality filter (often included in the kit) to maintain performance. Neglecting filter maintenance can negate the benefits.
3. **Possible ECU or Tuning Needs** Depending on the bike s stock ECU, the improved airflow may require a tune to prevent rich fueling conditions, which could lead to poor performance or increased emissions. Some riders report no issues, but others find they need a custom tune for optimal results.
4. **Cost** While not excessively expensive, the Arlen Ness kit is a premium aftermarket product. Prices typically range between $150 $250, depending on whether it includes a high-flow filter or additional components.
5. **Limited Off-Road Use** The inverted design is optimized for on-road use. In dusty or off-road conditions, the air cleaner may require more frequent cleaning or replacement of the filter to prevent clogging.
6. **Compatibility with Aftermarket Intakes** If you plan to add a cold air intake later, ensure the inverted air cleaner is compatible with it. Some setups may require additional modifications or spacers.
7. **Minor Installation Complexity** While generally straightforward, some riders may find the process slightly more involved than swapping a stock air cleaner, especially if they re not familiar with bike modifications.

### **Conclusion and Recommendation**
The **Arlen Ness MN/B0AX inverted air cleaner kit** is an excellent choice for a **2017 Harley-Davidson FXDL Sportster** if you re looking to improve airflow, horsepower, and throttle response. It strikes a balance between performance gains and practicality, with a reputation for reliability and ease of installation.
**For most riders**, the benefits such as better airflow, reduced backpressure, and a cleaner-running engine outweigh the minor drawbacks (like the need for filter maintenance or potential ECU tuning). If you re already running a performance exhaust or plan to add one, this kit will complement those upgrades effectively.
**Recommendation:**- **Install it if:** You want noticeable power gains, improved throttle response, and a more modern look without major modifications. Ensure you use the included or recommended high-quality filter and consider a tune if you notice rich fueling.
- **Skip it if:** You re on a tight budget, prefer minimal modifications, or plan to keep the bike stock with no other performance upgrades. In that case, a high-flow stock replacement or a simpler aftermarket cleaner may suffice.
**Final Verdict:** The Arlen Ness inverted air cleaner is a **solid upgrade** for the FXDL, particularly for riders who prioritize performance and airflow improvements. With proper maintenance, it can provide long-term benefits without significant drawbacks.
