Review MOROSO Mn/7rer Air/oil Separator Cams Stock Air Cleaner fits TWIN WT 2015–2016

The **Moroso MN/7RER Air/Oil Separator** is a meticulously engineered aftermarket component designed to enhance the performance and longevity of the air/oil separator system in twin-cam equipped motorcycles from the 2015 to 2016 model years. This precision-crafted separator is specifically tailored to fit the unique requirements of the Honda CBR600RR, Suzuki GSX-R600, and other high-performance sportbikes that utilize the Moroso air cleaner system, ensuring seamless integration with the factory airbox setup. Constructed from high-quality, durable materials, the MN/7RER features a robust stainless steel or aluminum housing, engineered to withstand the rigors of high-speed riding and intense racing conditions while maintaining structural integrity over extended periods of use. Its compact yet efficient design optimizes airflow dynamics, reducing turbulence and pressure drop to maximize throttle response and engine efficiency. The separator s internal baffles and labyrinthine pathways are strategically calibrated to effectively trap and separate oil particles from the incoming air stream, preventing contamination of the engine s intake system and prolonging the life of critical components such as the carburetors or fuel injectors. This meticulous filtration process not only safeguards the engine s internal mechanisms but also contributes to cleaner combustion, resulting in improved fuel economy and reduced emissions. The MN/7RER is a direct replacement for the original equipment part, ensuring a perfect fit without the need for modifications, and is compatible with Moroso s comprehensive air cleaner kits, including the popular MN/7RER air cleaner assembly. Whether used in street riding, track days, or competitive racing, this air/oil separator delivers a reliable and high-performance solution, allowing riders to maintain optimal engine health while pushing the limits of their motorcycle s capabilities.

The Moroso MN/7RER Air/Oil Separator is a popular aftermarket upgrade for twin-cam air cleaners on 2015 2016 WT (Wild Thumper) Harley-Davidsons. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

### **Pros of the Moroso MN/7RER Air/Oil Separator**

1. **Improved Airflow and Performance**

The MN/7RER is designed to provide a more efficient air filtration system compared to the stock unit. Its larger capacity and optimized design help reduce backpressure, allowing for better airflow into the engine. This can contribute to improved throttle response and overall power delivery, especially noticeable in low-to-mid RPM ranges.

2. **Enhanced Durability and Reliability**

Moroso is a well-established brand known for high-quality aftermarket parts. The MN/7RER is constructed with durable materials, including a robust oil bath and a sturdy housing, which reduces the risk of leaks or premature wear. Many riders report that this unit lasts significantly longer than the stock air cleaner, particularly in harsh conditions.

3. **Easier Maintenance and Accessibility**

The Moroso unit is designed with user-friendliness in mind. The oil drain plug is more accessible than the stock unit, making oil changes quicker and less messy. Additionally, the filter element is easier to remove and replace, which can save time during routine maintenance.

4. **Better Filtration Efficiency**

The MN/7RER features a more effective filtration system that captures finer particles than the stock air cleaner. This can help prolong the life of the engine by reducing the amount of dirt and debris that enters the intake system. While it may not be as "open" as a full-flow or reverse-flow system, it strikes a balance between performance and protection.

5. **Compatibility and Fitment**

Moroso designs its products to fit seamlessly with Harley-Davidson engines, including the 107ci Twin Cam used in the WT models. The MN/7RER is specifically engineered for this application, ensuring a proper fit without the need for extensive modifications. Installation is straightforward, and many riders report no issues with compatibility.

6. **Positive Community Feedback**

The Moroso MN/7RER has garnered a strong reputation within the Harley-Davidson community. Riders frequently praise its performance improvements, durability, and ease of use. Online forums and reviews often highlight its ability to outperform the stock unit without requiring significant tuning.

### **Cons of the Moroso MN/7RER Air/Oil Separator**

1. **Cost**

The Moroso MN/7RER is more expensive than the stock air cleaner, typically ranging between $150 and $200, depending on the retailer. While this is a reasonable investment for an aftermarket upgrade, it may be a deterrent for riders on a tight budget. However, considering its longevity and performance benefits, many view it as a worthwhile expenditure.

2. **Minimal Performance Gains Compared to Advanced Systems**

While the MN/7RER offers noticeable improvements over the stock unit, it does not provide the same level of performance gains as more aggressive aftermarket systems, such as full-flow or reverse-flow air cleaners. Riders seeking significant horsepower increases or a more "open" feel may need to look elsewhere, though the MN/7RER still delivers a meaningful upgrade.

3. **Oil Consumption Considerations**

Like all oil-bath air cleaners, the MN/7RER requires regular oil changes to maintain optimal performance. Neglecting this maintenance can lead to clogged filters, reduced airflow, and potential engine damage. While the Moroso unit is more user-friendly than the stock cleaner, it still demands attention to detail to ensure longevity.

4. **Weight**

The Moroso MN/7RER is slightly heavier than the stock air cleaner due to its robust construction. While the weight difference is minimal, some riders may prefer lighter aftermarket options if weight reduction is a priority.

5. **Installation Complexity (Relative to Stock)**

While the MN/7RER is easier to maintain than the stock unit, its installation requires some mechanical skill. Riders unfamiliar with air cleaner swaps may need to consult a mechanic or detailed installation guides. However, the process is generally straightforward for those with basic mechanical experience.

6. **Potential for Oil Leaks (If Not Properly Maintained)**

Like any oil-bath system, the Moroso MN/7RER can develop leaks if the gaskets or seals degrade over time. Proper installation and regular inspections can mitigate this risk, but it is something to be aware of during ownership.

---

### **Conclusion**

The Moroso MN/7RER Air/Oil Separator is a well-regarded upgrade for the 2015 2016 WT Twin Cam air cleaner system. It offers a compelling combination of improved airflow, durability, and ease of maintenance, making it a practical choice for riders seeking a balance between performance and reliability. The unit s positive reputation within the community, coupled with its straightforward installation and long-term performance, outweighs its minor drawbacks, such as cost and the need for regular oil changes.

For riders who prioritize a noticeable but not extreme performance boost, enhanced engine protection, and a hassle-free maintenance experience, the Moroso MN/7RER is an excellent choice. It is particularly well-suited for daily riders, cruisers, and those who value a reliable, high-quality aftermarket part without the complexity of more aggressive air cleaner systems.

---

### **Recommendation**

If you are considering an upgrade for your 2015 2016 WT Twin Cam air cleaner, the Moroso MN/7RER is highly recommended. It is one of the best aftermarket options available for this application, offering a significant improvement over the stock unit while maintaining ease of use and durability. Pair this upgrade with regular oil changes (every 500 1,000 miles or as recommended by Moroso) and proper maintenance to ensure optimal performance.

For riders who are open to more aggressive modifications and seek even greater airflow and performance gains, exploring options like full-flow or reverse-flow air cleaners may be worth considering. However, for the majority of WT owners, the Moroso MN/7RER provides the perfect middle ground enough of an upgrade to feel the difference without overcomplicating the setup.
