### **Pros and Cons of buying a Arlen Ness 7805-6021 Harley-Davidson CV Carb Teardrop ABS Air Cleaner Cover (Part #18-091)**

1. **Authentic Fit and Finish** The Arlen Ness brand is known for producing high-quality, aftermarket parts that closely match or exceed OEM standards. This air cleaner cover is designed to fit Harley-Davidson engines with CV carbs (common on models like the Sportster, Softail, and some V-Twin bikes) and is crafted to maintain a clean, factory-like appearance.

2. **Improved Airflow and Performance** The teardrop-shaped design of the ABS (Air Box System) air cleaner cover is optimized for better airflow, reducing restriction and allowing cleaner air to reach the carburetor. This can lead to improved throttle response and slightly better engine efficiency.

3. **Durability and Weather Resistance** The cover is likely made from durable materials (such as ABS plastic or reinforced polycarbonate) that resist cracking, warping, or degradation from heat, UV exposure, or moisture. This makes it a long-lasting upgrade compared to some generic aftermarket alternatives.

4. **Aesthetic Appeal** The sleek, teardrop shape is a stylish upgrade over stock air cleaner covers, giving the bike a more polished and modern look. It s a subtle but noticeable improvement for riders who value presentation.

5. **Easy Installation** As an OEM-style replacement, the part is designed to fit standard Harley-Davidson mounting points without requiring extensive modifications. Installation typically involves removing the old cover, cleaning the gasket surface, and securing the new one with the included hardware.

6. **Compatibility with ABS Systems** The "ABS" in the name indicates it s designed for Harley-Davidson s Air Box System, which is common on many modern and older bikes. This ensures proper sealing and airflow management, reducing the risk of vacuum leaks.

7. **Cost-Effective Upgrade** Compared to full carburetor rebuilds or engine modifications, this is a relatively inexpensive way to enhance airflow and appearance without significant trade-offs.

---

1. **Limited Compatibility** This specific part is designed for Harley-Davidson engines with **CV carbs (Chrysler-Vega carburetors)** and the **ABS air cleaner system**. It will **not** fit bikes with other carburetor types (e.g., Dell Orto, Mikuni, or Keihin) or those without an ABS system. Always verify compatibility with your bike s model and year before purchasing.

2. **Potential for Counterfeit Parts** The Arlen Ness brand is well-regarded, but counterfeit or low-quality knockoffs may exist in the aftermarket. Buying from an authorized dealer or a reputable online retailer (with verified seller ratings) reduces this risk.

3. **Minimal Performance Gain** While the teardrop shape improves airflow slightly, the performance boost is modest compared to other modifications (e.g., carb tuning, exhaust upgrades, or fuel system changes). It s more of an aesthetic and minor efficiency upgrade than a high-performance modification.

4. **Gasket Replacement Needed** Over time, the gasket between the air cleaner cover and the carburetor housing may wear out. While the cover itself is durable, you may need to replace the gasket periodically to maintain a proper seal and avoid vacuum leaks.

5. **Potential for Overheating in Extreme Conditions** If the air cleaner cover is not properly ventilated (though this design is generally well-ventilated), it could retain heat in very hot climates. However, this is rare with a quality ABS cover.

6. **No Noise Reduction Benefits** Unlike some aftermarket air intakes, this cover does not significantly reduce engine noise. It s purely for airflow and aesthetics.

7. **Installation May Require Cleaning** Before installing, the mounting surface and gasket area must be thoroughly cleaned to ensure a proper seal. Neglecting this step could lead to air leaks and reduced performance.
