Review MOROSO Mn/ekv8 Air/oil Separator Cams Vvo2 Air Cleaner Vs fits TWIN 2013

The **Moroso MN/EKV8 Air/Oil Separator** is a meticulously engineered aftermarket component designed to enhance the performance and longevity of the **Twin Cam V2 air cleaner system** found on 2013 Honda VSX 850 motorcycles. This high-quality separator serves as a critical interface between the air filter and the engine, ensuring that only clean, oil-free air enters the intake while efficiently capturing and retaining any residual oil mist that may escape from the air/oil filter housing. Crafted from durable materials, the Moroso separator features a robust, precision-machined design that guarantees a secure and leak-proof fit, preventing any unwanted oil from seeping into the intake tract. Its compact yet functional construction allows for seamless integration with the stock air cleaner setup, maintaining the VSX 850 s stock aesthetics while significantly improving its breathing efficiency. The separator s internal baffles and labyrinthine pathways are strategically optimized to maximize oil separation, reducing the risk of oil fouling the intake valves and cylinder walls common issues that can degrade engine performance and fuel economy over time. Whether used as part of a full air cleaner upgrade or as a standalone solution to address oil migration concerns, this Moroso component is a reliable choice for riders seeking both performance gains and long-term engine protection. Its compatibility with the 2013 VSX 850 s specific air cleaner system ensures a hassle-free installation, allowing enthusiasts to focus on optimizing their bike s handling and power delivery without compromising on reliability.

### Pros and Cons of buying a Moroso MN/EKV8 Air/Oil Separator for a Twin Cam VO2 Air Cleaner (2013)

#### **Pros:**

1. **Improved Engine Performance** The EKV8 air/oil separator helps maintain cleaner air intake by reducing oil carryover into the intake system. This can lead to better throttle response, smoother power delivery, and improved overall engine efficiency, especially in high-performance applications.

2. **Extended Air Cleaner Life** Oil contamination in the air cleaner element is a common issue with VO2-style air cleaners, particularly on older or high-mileage engines. The EKV8 separator reduces oil buildup, prolonging the life of the air filter and preventing clogging.

3. **Better Fuel Economy** A cleaner air intake means the engine receives the optimal air-to-fuel ratio, which can slightly improve fuel efficiency over time, especially if oil buildup was previously affecting airflow.

4. **Reduced Carbon Buildup** Oil in the intake system can lead to carbon deposits on intake valves and pistons, which the EKV8 helps mitigate. This can reduce the risk of carbon fouling, particularly in high-performance or aggressive driving scenarios.

5. **Easy Installation** The Moroso EKV8 is designed to fit directly onto the VO2 air cleaner housing, requiring minimal modifications. It integrates well with the stock setup, making it a straightforward upgrade.

6. **Durable Construction** Moroso products are generally well-built, and the EKV8 is no exception. It is made from materials that should withstand the demands of daily driving and performance use.

7. **Compatibility with Aftermarket Upgrades** If you plan to add a cold air intake, performance air filter, or other intake modifications, the EKV8 provides a solid foundation for those upgrades by keeping oil out of the system.

8. **Cost-Effective Solution** Compared to more extensive engine modifications, the EKV8 is a relatively inexpensive fix that can prevent more costly issues down the line, such as clogged air filters or carbon buildup.

#### **Cons:**

1. **Not a Permanent Fix for Oil Leaks** The EKV8 separator helps *contain* oil carryover but does not address the root cause of oil leaking into the air cleaner. If your engine has a failing PCV system, cracked gaskets, or excessive valve cover gasket leaks, the separator alone won t solve the problem. You may still need to address the source of the oil leak.

2. **Requires Regular Maintenance** While the separator reduces oil buildup, it doesn t eliminate it entirely. Over time, some oil may still accumulate, and you ll need to periodically clean or replace the separator s internal components (e.g., the oil drain plug or filter) to maintain optimal performance.

3. **Potential for Increased Backpressure** If the separator is not properly sized or installed, it could introduce slight backpressure into the intake system, which might slightly reduce airflow compared to a stock setup. However, this is usually negligible unless the separator is poorly designed or installed incorrectly.

4. **Limited Effect on Severe Oil Leaks** In cases of extreme oil leaks (e.g., a blown head gasket or severe valve cover leak), the EKV8 may not be sufficient on its own. You may still need to address the leak directly to fully resolve the issue.

5. **Compatibility with Some Modifications** If you have a highly aggressive intake setup (e.g., a deep-throated airbox or large-diameter downpipe), the EKV8 might not fit as neatly or could require additional modifications to integrate properly.

6. **Minimal Performance Gain for Stock Engines** On a stock or lightly modified engine, the performance improvement from the EKV8 may be subtle. The biggest benefits will be noticeable in high-mileage or heavily modified engines where oil buildup is already an issue.

---

### **Conclusion:**

The Moroso MN/EKV8 air/oil separator is a **highly recommended upgrade** for Twin Cam VO2 air cleaner setups, particularly on older or high-mileage engines where oil carryover is a known issue. It provides a practical, cost-effective solution to reduce oil contamination in the intake system, leading to cleaner air filters, improved throttle response, and potentially better long-term engine health.

However, it is **not a standalone fix for oil leaks**. If your engine has a persistent oil leak (e.g., from the valve cover, PCV system, or head gasket), you should address the source of the leak in addition to installing the EKV8. That said, for most riders looking to maintain or improve their air cleaner s performance without major modifications, the EKV8 is an excellent choice.

### **Recommendation:**

- **Install the EKV8** if you notice oil buildup in your air cleaner, experience sluggish throttle response, or want to prevent future issues with carbon buildup.

- **Check for oil leaks** before and after installation. If oil is still entering the intake system, investigate and repair the source (e.g., replace the valve cover gasket, PCV system, or head gasket as needed).

- **Combine with other maintenance** such as regular air filter replacements and occasional cleaning of the separator s internal components for optimal performance.

- **Consider pairing it with a high-quality performance air filter** (e.g., K&N, Mann, or Moroso s own high-flow filters) to further enhance airflow and engine efficiency.

For most riders, the EKV8 is a **worthwhile upgrade** that offers tangible benefits with minimal hassle. It s especially valuable for those who ride aggressively, modify their bikes, or have older engines prone to oil leaks.
