Review MOROSO Mor Air Oil Separators Performance Direct Fit Oem Replacement

The **Moroso 85533 Mor-Air Oil Separator** is a high-performance, precision-engineered component designed to enhance the efficiency and longevity of your vehicle s forced induction system, particularly in turbocharged applications. Engineered with meticulous attention to detail, this oil separator is crafted to effectively filter and remove oil vapors and particles from the intake air stream, ensuring cleaner airflow to the turbocharger and engine. By preventing oil contamination in the intercooler, intake manifold, and turbo bearings, the Mor-Air separator significantly reduces the risk of premature wear, carbon buildup, and reduced turbo efficiency common issues in high-performance and turbocharged setups. Constructed from durable materials, including a robust stainless steel or high-grade aluminum housing, this separator is built to withstand the demanding conditions of aggressive driving, high boost levels, and extended use without compromising structural integrity. Its innovative design incorporates a labyrinthine or baffled internal system, which maximizes oil separation while minimizing pressure drop, allowing for optimal airflow and turbo response. Whether installed in a daily driver, a performance-oriented vehicle, or a high-RPM engine, the Mor-Air separator is a critical upgrade for maintaining turbo health, improving throttle response, and extending the lifespan of your forced induction system. Its compatibility with a wide range of turbocharged applications from stock to heavily modified makes it a versatile and indispensable component for enthusiasts seeking peak performance and reliability.

**Pros and Cons of buying a Moroso 85533 Mor-Air Oil Separator**

The Moroso 85533 Mor-Air Oil Separator is a popular aftermarket component designed to improve engine performance by reducing oil contamination in the air intake system. Below is a detailed breakdown of its advantages and disadvantages.

### **Pros**

1. **Improved Engine Performance** By separating oil from the air-fuel mixture, this device helps maintain cleaner combustion, which can lead to better throttle response, smoother power delivery, and reduced carbon buildup on intake valves. Many users report noticeable gains in acceleration and overall engine efficiency.

2. **Reduced Oil Consumption** The Mor-Air system helps minimize oil leakage into the intake, which can lower oil consumption over time. This is particularly beneficial for high-mileage or heavily modified engines where oil burning is a concern.

3. **Compatibility with Turbocharged and Supercharged Engines** The Mor-Air system is designed to work effectively with forced induction setups, where oil carryover is more likely due to increased airflow and pressure. This makes it a valuable addition for turbocharged or supercharged applications.

4. **Easy Installation** The Mor-Air separator is designed to fit into existing intake systems with minimal modifications. It typically requires only basic tools and can be installed without extensive fabrication, making it accessible for DIY enthusiasts.

5. **Durability and Longevity** Moroso products are generally well-regarded for their quality and durability. The Mor-Air separator is made from materials that are resistant to heat and wear, ensuring long-term reliability.

6. **Cost-Effective Solution** Compared to more complex intake modifications or engine upgrades, the Mor-Air separator offers a relatively low-cost way to improve performance and protect engine components.

7. **Reduced Carbon Deposits** By preventing oil from entering the combustion chamber, the separator helps reduce carbon buildup on intake valves and pistons, which can improve engine longevity and maintain optimal compression ratios.

8. **Works with Aftermarket Intakes** The Mor-Air system is compatible with a wide range of aftermarket air intake systems, making it a versatile upgrade for those running performance intakes.

### **Cons**

1. **Limited Effect on Severe Oil Leaks** While the Mor-Air separator is effective at reducing oil carryover, it may not completely eliminate oil leaks in engines with significant internal issues (e.g., worn piston rings, valve seals, or PCV system failures). Users with severe oil consumption problems may still need additional repairs.

2. **Requires Proper Installation** Although installation is relatively straightforward, improper fitting or sealing can lead to leaks or reduced effectiveness. Ensuring a tight seal between the separator and intake system is crucial for optimal performance.

3. **Not a Standalone Performance Upgrade** The Mor-Air separator is not a power-adding device on its own. Its benefits are primarily related to intake cleanliness and reduced oil contamination. For significant performance gains, it should be paired with other modifications like cold air intakes, exhaust upgrades, or tuning.

4. **Potential for Increased Backpressure (If Misapplied)** In some cases, if the separator is installed incorrectly or if the intake system is not properly sized, it could introduce slight backpressure, which might slightly reduce airflow. However, this is rare if installed according to manufacturer guidelines.

5. **Maintenance Requirements** While not frequent, the separator may require occasional cleaning to ensure it continues to function effectively, especially in high-mileage or dusty environments.

6. **Compatibility Issues with Some Engines** Although widely compatible, the Mor-Air separator may not fit perfectly with every engine configuration, particularly those with unique intake designs or aftermarket modifications. Always verify compatibility before purchasing.

7. **Cost Relative to Other Modifications** While affordable, some enthusiasts may find that the benefits are modest compared to other performance upgrades, such as a full cold air intake or turbocharger upgrade.

### **Conclusion**

The Moroso 85533 Mor-Air Oil Separator is a practical and effective upgrade for engines prone to oil carryover, particularly in turbocharged or high-performance applications. Its primary strengths lie in improving intake cleanliness, reducing oil consumption, and protecting engine components from carbon buildup. For most drivers, the benefits outweigh the minor drawbacks, making it a worthwhile addition to an intake system.

However, it is not a magic solution for engines with severe internal issues, and its effectiveness depends on proper installation and compatibility with the vehicle s setup. If the goal is purely performance gains without addressing underlying oil leaks, other modifications may yield better results.

---

### **Recommendation**

- You have a turbocharged or supercharged engine and notice oil in the intake.

- You are running an aftermarket cold air intake and want to minimize oil contamination.

- Your engine experiences mild to moderate oil consumption, and you want to reduce it without major repairs.

- You are looking for a simple, cost-effective way to improve intake cleanliness and engine longevity.

- Your engine has severe oil leaks that require internal repairs (e.g., piston rings, valve seals).

- You are primarily seeking significant power gains rather than intake protection.

- Your intake system is not compatible with the Mor-Air separator, and you are unsure about installation.

- You prefer a more comprehensive performance package that includes tuning or exhaust upgrades.

**Final Verdict:** The Moroso 85533 Mor-Air Oil Separator is a solid, well-proven upgrade for reducing oil carryover and improving intake efficiency. It is particularly valuable for forced induction applications and is a low-risk addition to most performance intake setups. For best results, pair it with proper maintenance and ensure it is installed correctly.
