Review MOROSO Mn/9fck Air/oil Separator Cams Stock Air Cleaner Pa fits TWIN 2000–2017
The **Moroso MN/9F-CK Air/Oil Separator** is a meticulously engineered aftermarket component designed to enhance the performance and longevity of the stock air cleaner system on **2000 2017 Honda PA (Pilot/Airwave) models equipped with the Twin Cam engine**. This high-quality separator is specifically crafted to replace the factory air filter housing s internal oil bath system, ensuring superior filtration while minimizing oil carryover into the intake tract. Built with precision, the Moroso unit features a **durable, corrosion-resistant construction** that maintains structural integrity under the demanding conditions of daily driving, off-roading, or high-performance applications. Its **tight-sealing gasket design** guarantees a leak-proof connection to the air cleaner box, preventing unfiltered air from bypassing the filter media and preserving engine efficiency. The separator s **efficient oil drainage system** allows for optimal oil retention while effectively shedding excess moisture and contaminants, reducing the risk of clogged filters and maintaining consistent airflow. Whether used in stock configurations or integrated into a more aggressive intake setup, this separator is a reliable choice for riders seeking improved filtration without compromising on performance. Its **universal compatibility** with the Twin Cam s air cleaner system makes it an ideal upgrade for those looking to upgrade their stock setup while keeping maintenance simple and effective.
### **Pros and Cons of buying a Moroso MN/9FCK Air/Oil Separator for Twin Cam Air Cleaners (2000 2017 Honda PCX/PAL/PCX2/PAL2)**
#### **Pros:**1. **Compatibility** The Moroso MN/9FCK is specifically designed for Honda s Twin Cam air cleaner systems (2000 2017 models), ensuring a proper fit without modifications.
2. **Improved Airflow** The separator enhances airflow by filtering oil particles more effectively than stock setups, reducing clogging and maintaining engine efficiency.
3. **Durability** Moroso components are generally well-built, using high-quality materials that resist wear and corrosion over time.
4. **Easy Installation** The kit comes with clear instructions and is designed for straightforward installation, requiring minimal tools.
5. **Oil Separation Efficiency** The dual-stage filtration system (air filter oil separator) helps prevent oil from entering the carburetor or intake, reducing fouling and improving throttle response.
6. **Maintenance-Friendly** The separator can be cleaned or replaced separately from the air filter, making servicing easier than some integrated systems.
7. **Performance Benefits** Cleaner air intake leads to better combustion, which can improve fuel efficiency and reduce carbon buildup in the engine.
#### **Cons:**1. **Cost** While not excessively expensive, it is a premium aftermarket part compared to basic stock replacements or generic filters.
2. **Ongoing Maintenance** The oil separator requires periodic cleaning (every 5,000 10,000 miles, depending on riding conditions) to maintain effectiveness. Neglecting this can negate performance benefits.
3. **Potential for Leaks** If not installed correctly or if seals degrade over time, oil or air could leak, leading to contamination or reduced efficiency.
4. **Limited Longevity of Oil Separator Element** The oil-separating foam or mesh may degrade faster than the air filter, requiring replacement more frequently than the filter itself.
5. **Not a Complete Air Cleaner Upgrade** While the separator improves intake quality, it does not replace the need for a high-quality air filter (e.g., K&N, Micron Air) for optimal performance.
6. **Stock Replacement May Suffice for Light Riders** If you ride mostly in clean conditions and don t experience oil fouling, the stock air cleaner might last longer without needing this upgrade.

### **Conclusion**
The Moroso MN/9FCK air/oil separator is a solid choice for Twin Cam owners who want to enhance intake cleanliness, reduce oil fouling, and improve engine performance. It is particularly beneficial for riders who frequently operate in dusty or oily conditions, those who notice oil buildup in their carburetor, or anyone looking to extend the life of their air filter and intake system.
However, it requires regular maintenance to function optimally, and its benefits may be less critical for light riders in clean environments. If you prioritize long-term reliability and performance, the Moroso separator is a worthwhile investment. For budget-conscious riders or those who rarely encounter harsh conditions, a high-quality air filter alone might suffice.
### **Recommendation**
**Buy the Moroso MN/9FCK if:**- You ride in dusty, oily, or dirty conditions.
- You ve noticed oil fouling in your carburetor or intake.
- You want to improve airflow and engine efficiency.
- You re willing to perform regular maintenance (cleaning/replacing the separator element).
**Skip it if:**- You rarely ride in harsh conditions and your stock air cleaner works fine.
- You prefer a simpler, lower-maintenance solution.
- You re on a tight budget and can prioritize a high-quality air filter instead.
For best results, pair the Moroso separator with a performance air filter (e.g., K&N or Micron Air) and follow the manufacturer s maintenance schedule. This setup will provide the most significant benefits for your Twin Cam engine.
