---

### **Pros of the Cycle MN/2H7SS Air Cleaner Kit**

1. **Improved Airflow and Horsepower**

The kit replaces the stock air cleaner with a high-flow design, reducing restriction and allowing more air into the engine. This can lead to a noticeable increase in horsepower and torque, particularly in naturally aspirated applications like the Evo V. Many riders report a 5-10% gain, though results vary based on tuning and other modifications.

2. **Better Throttle Response**

With less restriction, the engine breathes more freely, resulting in quicker acceleration and a more responsive throttle. This is especially beneficial for riders who prioritize performance over stock feel.

3. **Durability and Quality Materials**

Cycle Engineering is known for using high-quality materials, including reinforced plastic and durable seals. The kit is designed to withstand the demands of long rides and high-performance use, reducing the risk of leaks or premature failure.

4. **Easy Installation**

The kit is designed for straightforward installation, often requiring minimal tools. It includes all necessary components (intake tubes, clamps, gaskets, etc.), and many riders complete the job in under an hour with basic mechanical skills.

5. **Aesthetic Appeal**

The kit features a sleek, modern design that improves the bike s appearance compared to the stock air cleaner. The black or matte finish blends well with aftermarket exhaust and intake systems.

6. **Compatibility with Other Modifications**

The MN/2H7SS is often paired with other Cycle Engineering products (e.g., intake manifolds, exhaust headers) and works well with tuners like **Harley-Davidson Performance Parts (Dyna Tuning)** or **Harley-Davidson Performance Tuning (HDP)**. This makes it a versatile choice for riders building out their bikes.

7. **Reduced Carbon Buildup**

The improved airflow helps prevent excessive carbon buildup on intake valves, which can occur with restrictive stock air cleaners. This contributes to better engine longevity and performance over time.

8. **Positive Community Feedback**

The kit has a strong reputation in the Harley-Davidson community, with many riders and mechanics endorsing it for its reliability and performance gains.

---

### **Cons of the Cycle MN/2H7SS Air Cleaner Kit**

1. **Potential for Increased Oil Consumption**

Like most high-flow air cleaner upgrades, the MN/2H7SS can lead to slightly higher oil consumption, especially if the engine is already running lean. This is more noticeable in older or high-mileage engines. Regular oil checks and potential adjustments to the carburetor (if equipped) or fuel system may be necessary.

2. **Requires Tuning for Optimal Performance**

While the kit itself is straightforward, pairing it with a stock ECU (in fuel-injected models) may not yield the best results. A **Harley-Davidson Performance Tuning (HDP) tune** or a **third-party tune (e.g., from a shop like Dyna Tuning or a custom tuner)** is often recommended to optimize fuel delivery and prevent running lean. Without tuning, the bike may feel rough or lose some of the intended gains.

3. **Noise Increase**

The high-flow design can make the engine slightly louder, particularly at higher RPMs. While not excessively loud, this may not be ideal for riders who prefer a quieter ride or are sensitive to noise.

4. **Cost Relative to Stock**

The MN/2H7SS kit is more expensive than the stock air cleaner, typically ranging between **$150 $250**, depending on the retailer. For riders on a tight budget, this may be a significant investment, though the performance gains often justify the cost.

5. **Potential for Leaks**

While Cycle Engineering products are generally reliable, improper installation (e.g., loose clamps, damaged seals) can lead to air leaks. This can negate performance gains and may require rechecking the installation after the first few rides.

6. **Not a "Set-and-Forget" Modification**

Unlike a simple air filter swap, the MN/2H7SS requires attention to maintenance. The oil level should be monitored more frequently, and the intake tubes should be inspected for cracks or wear over time.

7. **Limited Benefit Without Other Modifications**

While the kit provides noticeable gains on its own, the benefits are amplified when paired with other performance upgrades (e.g., headers, exhaust, or a performance cam). Riders expecting dramatic improvements without additional mods may be disappointed.

8. **Potential for Voiding Warranty (If Applicable)**

If your bike is still under warranty, installing an aftermarket air cleaner kit may void certain coverage, depending on the manufacturer s policies. Always check with your dealer before proceeding.

---

### **Conclusion**

The **Cycle MN/2H7SS Air Cleaner Kit** is one of the best aftermarket options for the **2005-2006 FLSTSCI Softail**, offering a balance of performance, durability, and ease of installation. It delivers measurable gains in airflow, throttle response, and horsepower, making it a worthwhile upgrade for riders who prioritize performance. However, it is not a "plug-and-play" solution it requires tuning to avoid running lean and may increase oil consumption. Additionally, while the kit is high-quality, it is not without cost, and proper installation is critical to avoid leaks.

For the **Evo V engine**, this kit is particularly well-suited because it complements other Cycle Engineering products and works well with modern tuning solutions. If you re building a performance bike or simply want to breathe new life into your Harley, the MN/2H7SS is a strong choice.

---

### **Recommendation**

- You want a **high-quality, performance-focused** air cleaner that improves airflow and throttle response.

- You are willing to **invest in tuning** (either through a dealer or a reputable tuner) to maximize gains.

- You plan to pair it with other modifications (e.g., headers, exhaust, or a performance cam).

- You value **durability and ease of installation** over minimal cost.

- You are on a tight budget and cannot afford the additional cost of tuning.

- Your bike is still under warranty, and you are concerned about voiding coverage.

- You prefer a **stock-like feel** and are not interested in performance upgrades.

- You cannot commit to regular oil checks or maintenance.

For the **2005-2006 FLSTSCI Softail**, the **Cycle MN/2H7SS is an excellent upgrade** that enhances performance without sacrificing reliability. With proper tuning and maintenance, it will provide noticeable gains and contribute to a more engaging ride. If you re serious about modifying your Harley, this kit is a smart investment.
