Review MOROSO Mn/a7jz Air/oil Separator Cams Stock Air Cleaner Tq fits TWIN 2008

The **Moroso MN/A7JZ Air/Oil Separator** is a meticulously engineered aftermarket component designed specifically to enhance the performance and longevity of the **Twin Cam air cleaner system** found on **2008 Harley-Davidson Sportster models equipped with the TQ engine**. This precision-crafted separator serves as a critical interface between the air cleaner and the engine s intake system, ensuring that only clean, oil-free air enters the combustion chamber while efficiently filtering out any residual oil mist that may escape from the air/oil induction setup. Built to exacting standards, the Moroso MN/A7JZ features a robust **stainless steel construction** with a **smooth, polished interior surface**, which minimizes turbulence and maximizes airflow efficiency critical for maintaining optimal throttle response and engine power. The separator s **universal compatibility** with the Twin Cam air cleaner system ensures a seamless fit, allowing for easy installation without the need for modifications to the stock intake setup. Whether you re a weekend cruiser seeking improved engine protection or a performance enthusiast looking to preserve the integrity of your air/oil induction system, this separator provides a reliable barrier against oil contamination, reducing wear on critical engine components like the carburetor, throttle body, and intake valves. Its durable design also contributes to a cleaner intake environment, which can help mitigate carbon buildup and improve overall engine efficiency over time. Backed by Moroso s reputation for quality and performance-focused engineering, the MN/A7JZ is an essential upgrade for any rider prioritizing both reliability and performance in their Harley-Davidson Sportster.

### Pros and Cons of buying a Moroso MN/A7JZ Air/Oil Separator for a Twin Cam Air Cleaner (2008 TQ)

#### **Pros:**

1. **Compatibility and Fit:** The Moroso MN/A7JZ is specifically designed for Honda Twin Cam engines, including the 2008 TQ model. It is engineered to fit seamlessly with the stock air cleaner housing, ensuring a proper seal and reducing the risk of leaks or improper installation.

2. **Improved Air/Oil Separation:** This separator is crafted to enhance the separation of oil from the air entering the engine. Twin Cam engines are known for their oil consumption issues, and a high-quality separator like this can help reduce oil contamination in the intake system, which can improve engine longevity and performance.

3. **Durability and Quality:** Moroso is a well-regarded brand in the motorcycle aftermarket, known for producing durable and reliable components. The MN/A7JZ is made from materials that are designed to withstand the rigors of daily riding, including heat, vibration, and exposure to the elements.

4. **Easy Installation:** The separator is designed to be a drop-in replacement for the stock air cleaner assembly. It typically requires minimal modification to the existing setup, making it a straightforward upgrade for most riders. Installation usually involves removing the old air cleaner, installing the new separator, and reconnecting the hoses.

5. **Performance Benefits:** By ensuring cleaner air enters the engine, the separator can contribute to better combustion efficiency. This may lead to improved throttle response, smoother power delivery, and reduced carbon buildup in the engine, which can enhance overall performance and reliability.

6. **Maintenance Convenience:** The design of the Moroso separator often includes features that make maintenance easier. For example, some models have accessible oil drain points or filters that can be cleaned or replaced without disassembling the entire air cleaner system.

7. **Compatibility with Aftermarket Upgrades:** If you plan to install aftermarket air filters or other modifications to your air cleaner system, the Moroso MN/A7JZ is likely to be compatible with these upgrades. This flexibility allows you to tailor the air cleaner system to your specific needs and preferences.

---

#### **Cons:**

1. **Cost:** The Moroso MN/A7JZ is not a low-cost upgrade. Depending on where you purchase it, the price can be higher than some generic or aftermarket alternatives. For riders on a tight budget, this may be a significant investment, especially if other upgrades are also needed.

2. **Potential Overkill for Stock Engines:** If your 2008 TQ is running stock with no significant modifications, the benefits of the Moroso separator might be marginal. Stock engines are generally less prone to oil consumption issues, and the separator s primary advantages may not be fully realized unless you are experiencing specific problems like excessive oil in the air filter or intake.

3. **Installation Complexity for Some Riders:** While the separator is designed for easy installation, some riders particularly those who are not mechanically inclined may find the process challenging. It requires careful handling to ensure proper sealing and alignment, and any mistakes could lead to leaks or improper function.

4. **Limited Customization:** The Moroso MN/A7JZ is a standardized product designed for a specific application. If you have unique modifications or a heavily customized air cleaner setup, you might need additional adapters or modifications to make it work perfectly, which could add to the complexity and cost.

5. **Maintenance Requirements:** Like any air/oil separator, the Moroso MN/A7JZ will require periodic maintenance. This includes checking and topping up the oil, cleaning or replacing the oil filter (if applicable), and ensuring the separator is free of debris. Neglecting maintenance could lead to reduced effectiveness and potential damage to the engine.

6. **Potential for Counterfeit Products:** When purchasing aftermarket parts, there is always a risk of buying counterfeit or low-quality replicas, especially if you are not buying from a reputable dealer. Always verify the authenticity of the product and purchase from trusted sources to avoid this issue.

7. **Weight and Bulk:** The Moroso separator, while functional, adds some weight and bulk to the air cleaner system. For riders who prioritize minimalism or lightweight components, this might be a minor drawback, though it is unlikely to have a significant impact on performance.

---

### **Conclusion:**

The Moroso MN/A7JZ air/oil separator is a high-quality, well-designed upgrade for the 2008 Honda TQ s Twin Cam air cleaner system. It offers clear benefits in terms of air/oil separation, durability, and compatibility, making it a solid choice for riders who are experiencing oil consumption issues or looking to enhance their engine s performance and longevity. The separator is particularly valuable for those who have modified their engines or are riding aggressively, as it helps mitigate the risks associated with oil contamination in the intake system.

However, the cost and potential overkill for stock engines are valid considerations. If your engine is running smoothly without noticeable oil issues, the benefits may not justify the expense. Additionally, the separator requires maintenance and careful installation, which might not be ideal for riders who prefer minimal upkeep or lack mechanical experience.

For riders who prioritize reliability, performance, and long-term engine health especially those with modified or heavily ridden TQs the Moroso MN/A7JZ is a worthwhile investment. If you are unsure whether the upgrade is necessary, consider monitoring your engine s oil consumption and air filter condition for a period before deciding.

### **Recommendation:**

If you are experiencing symptoms such as excessive oil buildup in your air filter, oil leaks into the intake, or reduced engine performance due to oil contamination, the Moroso MN/A7JZ is a strong recommendation. It is a proven solution that addresses these issues effectively and is backed by Moroso s reputation for quality.

For riders with stock engines that are running well without oil-related problems, the upgrade may not be essential. In such cases, focus on other maintenance tasks like regular oil changes, air filter cleaning, and general upkeep to ensure optimal engine health.

Ultimately, weigh the pros and cons against your specific riding conditions, engine modifications, and budget. If you decide to proceed, purchase the separator from an authorized Moroso dealer or a trusted aftermarket parts supplier to ensure authenticity and quality. Follow the installation instructions carefully and perform regular maintenance to maximize the separator s effectiveness.
