Review REIN Separator To Intake Crankcase Breather Hose Volkswagen At fits 2008–2013

The **Rein SX-Z7R9 Separator Intake Crankcase Breather Hose** is a high-performance, precision-engineered replacement part designed specifically for Volkswagen vehicles manufactured between 2008 and 2013, including models equipped with turbocharged or high-performance engines. This meticulously crafted hose serves as a critical component of the vehicle s crankcase ventilation system, ensuring proper oil and moisture separation while maintaining optimal engine breathing efficiency. Constructed from durable, heat-resistant synthetic rubber, the Rein SX-Z7R9 is engineered to withstand the demanding conditions of high-performance driving, preventing oil leaks, carbon buildup, and harmful blow-by gases from entering the intake system. The integrated separator technology within the hose effectively filters out contaminants, protecting the engine s internal components while reducing emissions and improving overall engine longevity. This upgrade is particularly beneficial for turbocharged engines, where excessive crankcase pressure can lead to premature wear and reduced performance. With its precise fit and robust construction, the Rein SX-Z7R9 is an ideal choice for enthusiasts seeking to enhance reliability, maintain engine health, and optimize airflow in their Volkswagen vehicles.

### **Pros and Cons of buying a Rein SX-Z7R9 Separate Intake Crankcase Breather Hose for 2008 2013 Volkswagen Models**

#### **Pros:**

The Rein SX-Z7R9 separator intake crankcase breather hose is a popular aftermarket upgrade for Volkswagen engines (particularly 2.5L and 3.6L V6 models) due to several key advantages:

1. **Improved Engine Breathing and Performance**

The hose separates oil vapors from the crankcase breather system, reducing oil consumption and preventing carbon buildup in the intake manifold and cylinders. This can lead to better throttle response, smoother power delivery, and improved overall engine efficiency.

2. **Reduced Oil Contamination**

Unlike stock hoses, which allow oil vapors to mix with intake air, the Rein separator filters out oil particles before they enter the engine. This helps prevent oil fouling of intake valves, spark plugs, and combustion chambers, which is a common issue in high-mileage or poorly maintained VWs.

3. **Extended Engine Life**

By minimizing oil leakage into the intake system, the separator reduces carbon deposits that can restrict airflow and reduce compression over time. This can contribute to longer engine longevity, especially in vehicles prone to oil consumption.

4. **Easier Installation**

The Rein part is designed as a direct replacement for the stock crankcase breather hose, requiring minimal modifications. It connects to the existing breather system without requiring additional tools or adjustments, making it a straightforward DIY-friendly upgrade.

5. **Compatibility with Turbocharged and Naturally Aspirated Engines**

The separator works effectively on both turbocharged (e.g., 2.5T, 3.6T) and naturally aspirated (e.g., 3.6L FSI) VW engines, making it a versatile solution for a wide range of models.

6. **Positive User Feedback and Reputation**

Rein is a well-regarded brand in the aftermarket performance and maintenance sector, with many owners reporting noticeable improvements in engine cleanliness and performance after installation.

---

#### **Cons:** While the Rein separator offers significant benefits, there are a few potential drawbacks to consider:

1. **Cost Relative to Stock**

The Rein SX-Z7R9 hose is more expensive than the stock OEM part, typically ranging between $30 and $60 depending on the retailer. For budget-conscious buyers, this may be a deterrent, especially if the stock system is still functioning adequately.

2. **Mixed Results on Oil Consumption**

While the separator reduces oil vapor leakage into the intake, it does not address underlying engine issues that cause excessive oil consumption (e.g., worn piston rings, valve seals, or PCV system failures). If the engine is already burning oil, the separator may only provide temporary relief until the root cause is addressed.

3. **Potential for Leaks or Improper Sealing**

Like any aftermarket part, improper installation or low-quality seals can lead to leaks. Users must ensure the hose is securely connected to the breather system and that the clamps are tight to prevent air or oil from escaping.

4. **Limited Effect on Carbon Buildup in Existing Engines**

If the engine already has significant carbon deposits from years of oil fouling the intake, the separator alone may not fully reverse the damage. In such cases, additional maintenance (e.g., intake cleaning or valve polishing) may be required.

5. **Not a Universal Fix for All Engine Issues**

The separator is specifically designed to address crankcase breather-related problems. If the engine has other issues (e.g., turbo failure, fuel system problems, or mechanical wear), the separator will not resolve those issues on its own.

---

### **Conclusion**

The Rein SX-Z7R9 separator intake crankcase breather hose is a highly effective and practical upgrade for 2008 2013 Volkswagen owners looking to improve engine breathing, reduce oil contamination, and extend engine life. Its ease of installation, compatibility with various engine types, and positive user experiences make it a strong recommendation for those experiencing or wanting to prevent oil-related intake issues.

However, it is not a magic solution for all engine problems. If the engine is already burning oil excessively or has severe carbon buildup, the separator should be paired with other maintenance steps (e.g., checking for oil leaks, replacing worn seals, or performing an intake cleaning). For most owners who notice oil residue in the intake or want to proactively maintain their engine, the Rein separator is a worthwhile investment.

### **Recommendation**

**Buy the Rein SX-Z7R9 separator if:**

- You notice oil residue in the intake manifold or on spark plugs.

- Your engine has been running with a stock crankcase breather for a long time and you want to prevent future carbon buildup.

- You are performing routine maintenance and want to improve engine efficiency.

- You are comfortable with a straightforward DIY installation.

**Avoid or reconsider if:**

- Your engine is burning oil excessively, and you haven t identified or fixed the source of the leak.

- You are on a tight budget and the stock system is still functioning without issues.

- You expect the separator to replace other necessary maintenance (e.g., valve cleaning, turbo inspection).

For most Volkswagen owners in the specified model range, the Rein separator is a smart, low-risk upgrade that can pay dividends in engine performance and longevity.
