Whether you're cruising on the highway or tackling twisty backroads, this air cleaner kit provides a cleaner, more efficient breathing system that complements the raw power of your Harley s big twin engines.

The **Arlen Ness MN/007W Inverted Air Cleaner Kit** is a popular aftermarket upgrade for Harley-Davidson engines, including the **1988-2003 FK series (e.g., FLT, FLH, FLSTA, etc.)**. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

### **Pros of the Arlen Ness MN/007W Inverted Air Cleaner Kit**

1. **Improved Airflow and Horsepower**

The inverted design eliminates restrictive elements found in stock air cleaners, allowing for better airflow into the engine. Many riders report noticeable gains in horsepower and throttle response, particularly in stock or mildly modified engines. The kit is designed to reduce backpressure, which can help the engine breathe more efficiently.

2. **Enhanced Durability and Reliability**

Arlen Ness components are known for their high-quality construction, often using materials like aluminum and reinforced plastics. The inverted design reduces the risk of oil leaks and contamination, as the oil bath is more contained and less prone to sloshing or spillage compared to traditional top-mounted air cleaners.

3. **Easier Maintenance and Accessibility**

The inverted design places the air cleaner closer to the ground, making it easier to access for cleaning or oil changes. This can be particularly useful in situations where the bike is parked on uneven surfaces or in tight spaces. The oil drain is also more straightforward to manage.

4. **Better Heat Dissipation**

The inverted position helps keep the air cleaner cooler, as it is less exposed to engine heat. This can reduce the risk of oil breakdown and improve overall longevity of the air filter media.

5. **Aesthetic Appeal**

The kit includes a sleek, modern-looking air cleaner that many riders prefer over the stock, utilitarian design. It can enhance the bike s appearance, especially when paired with other aftermarket components.

6. **Compatibility with Performance Mods**

The MN/007W is designed to work well with other performance upgrades, such as high-flow exhausts, camshafts, or fuel system modifications. It provides a balanced upgrade path for riders looking to enhance their bike s performance without drastic changes.

7. **Reduced Oil Consumption**

Unlike some aftermarket air cleaners that can increase oil consumption due to poor sealing or excessive airflow, the Arlen Ness kit is engineered to maintain proper oil levels while still improving performance.

---

### **Cons of the Arlen Ness MN/007W Inverted Air Cleaner Kit**

1. **Cost**

The Arlen Ness kit is more expensive than the stock air cleaner or some generic aftermarket alternatives. While it is a premium product, the price may be a deterrent for budget-conscious riders or those who only want minor improvements.

2. **Installation Complexity**

Installing the inverted air cleaner requires some mechanical skill and may involve modifications to the stock mounting bracket or hoses. Riders without experience may need to consult a mechanic or follow detailed instructions carefully to avoid leaks or improper sealing.

3. **Potential for Oil Leaks**

While the inverted design is generally more reliable, improper installation or low oil levels can still lead to leaks. The oil bath must be maintained at the correct level to prevent the engine from running dry or the filter from becoming contaminated with oil.

4. **Limited Stock Replacement Parts**

If something goes wrong with the Arlen Ness kit, finding replacement parts or service manuals may be more difficult than for OEM components. Arlen Ness does offer support, but it may not be as readily available as Harley-Davidson s dealer network.

5. **Not a "Set and Forget" Solution**

The kit requires regular maintenance, including oil changes and filter inspections. Neglecting maintenance can lead to reduced performance, increased oil consumption, or even engine damage if the filter becomes clogged or the oil level drops too low.

6. **Potential for Increased Noise**

Some riders report that the inverted air cleaner can make the engine slightly louder, particularly at higher RPMs. While this is subjective, it may not be desirable for those who prefer a quieter ride.

7. **Compatibility Issues with Some Mods**

While the MN/007W is designed to work with many performance mods, it may not be ideal for extremely high-flow setups (e.g., aggressive camshafts, large carburetors, or turbocharging). In such cases, additional modifications (e.g., larger air intakes or different filter media) may be necessary.

---

### **Conclusion**

The **Arlen Ness MN/007W Inverted Air Cleaner Kit** is one of the best aftermarket options for Harley-Davidson FK series bikes, offering significant benefits in terms of airflow, durability, and ease of maintenance. It is particularly well-suited for riders who want a balance of performance improvement and reliability without drastic modifications. However, it is not without drawbacks, including its cost, installation complexity, and the need for regular upkeep.

For riders who prioritize **performance, longevity, and a modern aesthetic**, the MN/007W is an excellent choice. For those on a tight budget or who prefer minimal modifications, a stock air cleaner or a simpler aftermarket alternative might be more appropriate.

---

### **Recommendation**

- You want a noticeable improvement in airflow and horsepower.

- You value durability and ease of maintenance.

- You are willing to invest in a high-quality aftermarket part.

- You plan to pair it with other performance upgrades (e.g., exhaust, camshafts).

- You prefer the inverted design for aesthetic or practical reasons.

- You are on a tight budget and can achieve similar results with a less expensive kit.

- You lack mechanical experience and are uncomfortable with installation or maintenance.

- You plan to run extreme performance mods that may require additional air intake solutions.

- You prioritize stock simplicity and do not want to modify your bike significantly.

**Final Verdict:** The Arlen Ness MN/007W is a **highly recommended upgrade** for FK series Harley-Davidson owners who want a reliable, performance-enhancing air cleaner. With proper installation and maintenance, it can provide years of trouble-free use and noticeable gains in power and efficiency.
